The mathematics of general relativity refers to various mathematical structures and techniques that are used in studying and formulating Albert Einstein's theory of general relativity.
 The main tools used in this geometrical theory of gravitation are tensor fields defined on a Lorentzian manifold representing spacetime.
 This article is a general description of the mathematics of general relativity.
Tests of general relativity serve to establish observational evidence for the theory of general relativity.
 The first three tests, proposed by Einstein in 1915, concerned the "anomalous" precession of the perihelion of Mercury, the bending of light in gravitational fields, and the gravitational redshift.
 The precession of Mercury was already known; experiments showing light bending in line with the predictions of general relativity was found in 1919, with increasing precision measurements done in subsequent tests, and astrophysical measurement of the gravitational redshift was claimed to be measured in 1925, although measurements sensitive enough to actually confirm the theory were not done until 1954.
 A program of more accurate tests starting in 1959 tested the various predictions of general relativity with a further degree of accuracy in the weak gravitational field limit, severely limiting possible deviations from the theory.
In geometry and physics, spinors are elements of a (complex) vector space that can be associated with Euclidean space.
 Like geometric vectors and more general tensors, spinors transform linearly when the Euclidean space is subjected to a slight (infinitesimal) rotation.
 When a sequence of such small rotations is composed (integrated) to form an overall final rotation, however, the resulting spinor transformation depends on which sequence of small rotations was used: "unlike" vectors and tensors, a spinor transforms to its negative when the space is rotated through a complete turn from 0° to 360° (see picture).
 This property characterizes spinors.
 It is also possible to associate a substantially similar notion of spinor to Minkowski space in which case the Lorentz transformations of special relativity play the role of rotations.
 Spinors were introduced in geometry by Élie Cartan in 1913.
 In the 1920s physicists discovered that spinors are essential to describe the intrinsic angular momentum, or "spin", of the electron and other subatomic particles.
The Pound–Rebka experiment is a well known experiment to test Albert Einstein's theory of general relativity.
 It was proposed by Robert Pound and his graduate student Glen A. Rebka Jr. in 1959, and was the last of the classical tests of general relativity to be verified (in the same year).
 It is a gravitational redshift experiment, which measures the redshift of light moving in a gravitational field, or, equivalently, a test of the general relativity prediction that clocks should run at different rates at different places in a gravitational field.
 It is considered to be the experiment that ushered in an era of "precision" tests of general relativity.
Sir Roger Penrose {'1': ", '2': ", '3': ", '4': "} (born 8 August 1931) is an English mathematical physicist, mathematician and philosopher of science.
 He is the Emeritus Rouse Ball Professor of Mathematics at the Mathematical Institute of the University of Oxford, as well as an Emeritus Fellow of Wadham College.
Ashtekar variables, which were a new canonical formalism of general relativity, raised new hopes for the canonical quantization of general relativity and eventually led to loop quantum gravity.
 Smolin and others independently discovered that there exists in fact a Lagrangian formulation of the theory by considering the self-dual formulation of the Tetradic Palatini action principle of general relativity.
 These proofs were given in terms of spinors.
 A purely tensorial proof of the new variables in terms of triads was given by Goldberg and in terms of tetrads by Henneaux et al.
 Here we in particular fill in details of the proof of results for self-dual variables not given in text books.
Moshe Carmeli (Hebrew: משה כרמלי‎ ‎ , 1933–2007) was the Albert Einstein Professor of Theoretical Physics, Ben Gurion University (BGU), Beer Sheva, Israel and President of the Israel Physical Society.
 He received his D.Sc.
 from the Technion-Israel Institute of Technology in 1964.
 He became the first full professor at BGU's new Department of Physics.
 He did significant theoretical work in the fields of cosmology, astrophysics, general and special relativity, gauge theory, and mathematical physics, authoring 4 books, co-authoring 4 others, and publishing 128 refereed research papers in various journals and forums, plus assorted other publications (146 in all).
 He is most notable for his work on gauge theory and his development of the theory of cosmological general relativity, which extends Einstein's theory of general relativity from a four-dimensional spacetime to a five-dimensional space-velocity framework.
Wolfgang Rindler (born 18 May 1924, Vienna) is a physicist working in the field of General Relativity where he is known for introducing the term "event horizon", Rindler coordinates, and (in collaboration with Roger Penrose) for popularizing the use of spinors in general relativity.
 He is also a prolific textbook author.
Relativistic Newtonian dynamics (RND) is an extension of Newtonian dynamics that overcomes its shortcomings by considering the influence of potential energy on space and time using some principles of Einstein's theories of special and general relativity.
 In its current form, it models the motion of objects with non-zero mass as well as massless particles under the attraction of a time independent conservative force in some inertial frame.
 Unlike general relativity, RND is not restricted solely to a gravitational potential and does not require the exigency of curving spacetime.
 Created in 2015, the centennial year of Einstein's general relativity, by Israeli scientists Yaakov Friedman in collaboration with Joseph Steiner, RND predicts accurately both classical and modern tests of general relativity, such as, the perihelion precession of Mercury (planet) which agree with the known observed perihelion prcession, the periastron advance of a binary star, which is identical to the post-Keplerian equation of the relativistic advance of the periastron in a binary, gravitational lensing which is identical to Einstein's formula for weak gravitational lensing using GR, and light travel (Shapiro delay) time delay which agree with the known formula for the Shapiro time delay, confirmed experimentally by several experiments
The Proceedings of A. Razmadze Mathematical Institute is a peer-reviewed scientific journal published by the A. Razmadze Mathematical Institute.
 The journal is the continuation of "Tbilisis Mathematikuri Institutis Shromebi" ("Trudy Tbilisskogo Matematicheskogo Instituta", "Travaux de L'Institut Mathematique de Tbilissi") and was established in 1937.
 It carries its current name as of volume 100.
 The journal is named for Georgian mathematician Andrea Razmadze, one of the original four of the Mathematical Institute, and a co-founder of Tbilisi State University.
