A brief review of aspects of gravity gauge theory correspondance inspired by string theory is presented.
We discuss the nature and a general formulation of the relativity principle and we show that it can be justified starting from a strictly operational point of view. We give some remark on the connection with the spacetime symmetry groups.…
A portrait of Kurt Goedel with emphasis on his work on relativity theory and idealistic philosophy.
In Appendix B, there is a proposal about the Limb Effect which could be of great significance for Solar Physics. In his PRINCIPLE OF RELATIVITY, Cambridge University Press, 1922 (republished Dover, 2004) A. N. Whitehead, making no use of…
The goal of this lecture is to introduce the student to the theory of Special Relativity. Not to overload the content with mathematics, the author will stick to the simplest cases; in particular only reference frames using Cartesian…
I provide a very brief sketch of some of Dirac's interests and work in gravity, particularly his Hamiltonian formulation of Einstein's theory and its relation to his earlier research.
These Lecture notes give an introduction to Regge calculus as a discrete model of General Relativity.
Lecture notes on selected topics in the theory of gravitation.
We review the life and remarkable contributions to Physics of Gregor Wentzel.
A modest aim of this pedagogical presentation is to analyze, critically, certain fundamental physical concepts to illustrate the physical principles behind the special theory of relativity and, hence, to also illustrate the limitations of…
An outline of J\"org Eschmeier's main mathematical contributions is organized both on a historical perspective, as well as on a few distinct topics. The reader can grasp from our essay the dynamics of spectral theory of commutative tuples…
These notes on string theory are based on a series of talks I gave during my graduate studies. As the talks, this introductory essay is intended for young students and non-string theory physicists.
We shortly review the state of art and perspectives of Extended Theories of Gravity.
Simple physical models of a measuring rod and of a clock are used to demonstrate the contraction of objects and clock retardation in special relativity. It is argued that the models could help in promoting student understanding of special…
It is hoped that these lectures will give a point of entry into that vast web of related ideas that go under the name "string theory". I start with a more or less qualitative introduction to gravity as a field theory and sketch how one…
These lectures are a brief introduction to supersymmetry.
We review the physics at the end of the nineteenth century and summarize the process of the establishment of Special Relativity by Albert Einstein in brief. Following in the giant's footsteps, we outline the scientific method which helps to…
The talk presents the main lines of biography of the prominent physicist and bright personality. Also given is a necessarily brief description of Gribov's scientific work.
We provide an introduction to selected recent advances in the mathematical understanding of Einstein's theory of gravitation.
The first two lectures are devoted to describing the basic concepts of scattering theory in a very compressed way. A detailed presentation of the abstract part can be found in \cite{I} and numerous applications in \cite{RS} and \cite{Y2}.…
