Translation of Lobachevsky’s papers on non-Euclidean geometry

Nikolai I. Lobachevsky, The Foundations of Geometry: Works on Non-Euclidean Geometry (Minkowski Institute Press, Montreal 2019), 210 pages


Neither general relativity (which revealed that gravity is merely manifestation of the non-Euclidean geometry of spacetime) nor modern cosmology would have been possible without the almost simultaneous and independent discovery of non-Euclidean geometry in the 19th century by three great mathematicians – Nikolai Ivanovich Lobachevsky, Janos Bolyai and Carl Friedrich Gauss (whose ideas were later further developed by Georg Friedrich Bernhard Riemann).

This volume contains three works by Lobachevsky on the foundations of geometry and non-Euclidean geometry: “Geometry”, “Geometrical investigations on the theory of parallel lines” and “Pangeometry”. It will be of interest not only to experts and students in mathematics, physics, history and philosophy of science, but also to anyone who is not intimidated by the magnitude of one of the greatest discoveries of our civilization and would attempt to follow (and learn from) Lobachevsky’s line of thought, helpfully illustrated by over 130 figures, that led him to the discovery.

Black holes and neutron stars in modified gravity, Meudon, France

Thanks to the advent of gravitational wave astronomy (LIGO, Virgo, KAGRA, LISA), as well as to high-angular-resolution observations of black hole vicinity (EHT, VLTI/GRAVITY), new tests of gravity in the strong field regime are becoming available. They offer the potentiality to discriminate between general relativity and alternative theories (generically designed as modified gravity) that are currently developed, notably to address the issue of dark energy in cosmology.

This workshop is devoted to the properties of compact objects (black holes, neutron stars, boson stars, etc.) in these theories and will allow ample time for discussions.

Registration is free but we ask all participants to register on the workshop’s webpage.

The 20th BritGrav meeting will be hosted by the School of Mathematics and Statistics at University College Dublin.

The aim of this two-day meeting, to be held on Monday 27 April and Tuesday 28 April 2020, is to bring together early-stage researchers working on all aspects of gravitational physics, including astrophysics, cosmology, general relativity, quantum gravity, gravitational-wave data analysis and instrumentation, in the spirit of collaboration and the free exchange of results and ideas.

In keeping with BritGrav tradition, the meeting will consist of short talks with priority given to PhD students and early-career researchers. Participants are responsible for their own meals, travel and accommodation. Limited funding is provided by the IOP Gravitational Physics Group, to support travel for students.

Registration is free, and the deadline for application for financial support and abstract submission is 15 March 2020.

At the end of the meeting, we will award The Best Student Talk Prize, sponsored by the IOP Publishing Group.

Local Organisers: Barry Wardell, Adrian Ottewill, Niels Warburton, Sarp Akcay, Conor O’Toole, Josh Mathews, Leanne Durkan, Benjamin Leather, Philip Lynch and Kevin Kiely.

Living Reviews in Relativity: “The causal set approach to quantum gravity”

The open-access journal Living Reviews in Relativity has published a new review article on 27 September 2019:

Sumati Surya,
“The causal set approach to quantum gravity”,
Living Rev Relativ (2019) 22:5

The causal set theory (CST) approach to quantum gravity postulates that at the most fundamental level, spacetime is discrete, with the spacetime continuum replaced by locally finite posets or “causal sets”. The partial order on a causal set represents a proto-causality relation while local finiteness encodes an intrinsic discreteness. In the continuum approximation the former corresponds to the spacetime causality relation and the latter to a fundamental spacetime atomicity, so that finite volume regions in the continuum contain only a finite number of causal set elements. CST is deeply rooted in the Lorentzian character of spacetime, where a primary role is played by the causal structure poset. Importantly, the assumption of a fundamental discreteness in CST does not violate local Lorentz invariance in the continuum approximation. On the other hand, the combination of discreteness and Lorentz invariance gives rise to a characteristic non-locality which distinguishes CST from most other approaches to quantum gravity. In this review we give a broad, semi-pedagogical introduction to CST, highlighting key results as well as some of the key open questions. This review is intended both for the beginner student in quantum gravity as well as more seasoned researchers in the field.

Tenure-track assistant professor in gravitational physics and astrophysics at the University of Mississippi, USA

The Department of Physics and Astronomy at the University of Mississippi invites applications for a tenure-track assistant professor position in gravitational physics and astrophysics for the Fall of 2020. We seek candidates from any area that complements or diversifies the research interests of our gravitational physics group (faculty members Bombelli, Gupta, and Stein) with expertise in gravitational-wave source modeling, tests of general relativity, quantum gravity, and cosmology, who are members of the LIGO and the Simulating eXtreme Spacetimes (SXS) collaborations. The successful candidate will also join the recently established Center for Multimessenger Astrophysics. Candidates are expected to develop a research program capable of supporting and leading graduate students to a Ph.D. A competitive startup package is available in the first three years. A Ph.D. in Physics or a related field is required. Faculty members are expected to contribute to the teaching and service activities of the Department and the University. Teaching duties include up to three courses a year at the undergraduate and/or graduate level.

Interested candidates should apply online at and submit a curriculum vitae, a statement of teaching philosophy, a detailed proposal for developing their research program, and the names of three references who can provide letters of recommendation. Inquiries can be sent to the email address or to Gravity Search Committee Chair, Department of Physics and Astronomy, The University of Mississippi, P.O. Box 1848, University, MS 38677. Consideration of applications will begin on November 11, 2019, but applications will be accepted until an adequate applicant pool is established or until the position is filled.

Applications from underrepresented groups in physics are strongly encouraged. The department is committed to increasing diversity in the field. The University of Mississippi complies with all applicable laws regarding equal opportunity and affirmative action and does not unlawfully discriminate against any employee or applicant for employment on the basis of race, color, gender, sex, sexual orientation, gender identity or expression, religion, national origin, age, disability, veteran status or genetic information.

Gravitational Wave Astronomy Postdoc at Montana State, Bozeman, USA

The Department of Physics of Montana State University invites applications for a 3-year postdoctoral position in Gravitational Wave Astronomy with an emphasis on Bayesian Inference and AstroStatistics.

The successful candidate will work with Prof. Neil Cornish and his group in the eXtreme Gravity Institute ( at Montana State University. The eXtreme Gravity Institute (XGI) is composed of faculty members Neil Cornish, Bennett Link, Anne Lohfink, Amy Reines, Sachiko Tsuruta and David Nidever. The XGI hosts international workshops and summer schools on topics related to extreme gravity. The institute is also deeply involved in public outreach, formal and informal education.

For the job announcement and application portal see:

Members of the eXtreme Gravity Institute are leaders in the application of Bayesian Inference and machine learning to develop new tools for gravitational wave astronomy.
The position is NASA funded, with the goal of developing a comprehensive science analysis approach for the future Laser Interferometer Space Antenna (LISA). Prof. Cornish is a member of the LISA, LIGO and NANOGrav collaborations, and opportunities will be available to conduct research across the gravitational wave spectrum.
