Charges in the extended BMS algebra: Definitions and applications

چکیده
This is a review of selected topics from recent work on symmetry charges in asymptotically flat spacetime done by the author collaboration with U. Kol and R. Javadinezhad. First we reinterpret reality constraint boundary graviton as gauge fixing new local symmetry, called dual supertranslations. extends BMS group bears many similarities to (magnetic) electrodynamics. We use this propose description TAUB-NUT space that does not contain closed time-like curves. Next summarize progress towards definition Lorentz super-Lorentz commute supertranslations soft mode.

Non-Relativistic BMS algebra
We construct two possible candidates for the non-relativistic bms4 algebra in four space-time dimensions by contracting the original relativistic bms4 algebra. The bms4 algebra is infinitedimensional and it contains the generators of the Poincaré algebra, together with the so-called super-translations. Similarly, the proposed nrbms4 algebras can be regarded as two infinitedimensional extensions...
متن کاملSome extended Simpson-type inequalities and applications
In this paper, we shall establish some extended Simpson-type inequalities for differentiable convex functions and differentiable concave functions which are connected with Hermite-Hadamard inequality. Some error estimates for the midpoint, trapezoidal and Simpson formula are also given.

the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولExtended Jacobi and Laguerre Functions and their Applications
The aim of this paper is to introduce two new extensions of the Jacobi and Laguerre polynomials as the eigenfunctions of two non-classical Sturm-Liouville problems. We prove some important properties of these operators such as: These sets of functions are orthogonal with respect to a positive de nite inner product de ned over the compact intervals [-1, 1] and [0,1), respectively and also th...
