Vor 5 Tagen · Henri Poincaré (born April 29, 1854, Nancy, France—died July 17, 1912, Paris) was a French mathematician, one of the greatest mathematicians and mathematical physicists at the end of 19th century. He made a series of profound innovations in geometry, the theory of differential equations, electromagnetism, topology, and the ...
Vor 5 Tagen · For over 170 years, the connection between group theory and the fields of geometry and topology has held central in mathematics—the connection is that the symmetries of a geometric object form a group. Mathematics is only a story of groups. (H. Poincaré)
Vor 5 Tagen · A French mathematician, physicist, engineer and philosopher of science, Poincaré was a scientific giant in the late 19th and early 20th century. Known as “The Last Universalist”, he made ...
Vor 4 Tagen · We propose Feynman rules to calculate the Carrollian amplitude where the Fourier transforms emerge as the integral representation of the external lines in the Carrollian space. Then we study the four-point Carrollian amplitude at loop level in massless Φ 4 theory. As a consequence of Poincaré invariance, the four-point Carrollian amplitude ...
Vor 5 Tagen · Abstract. Two-dimensional Poincaré maps are widely used for discovering planar periodic and quasi-periodic orbits. These maps have well-defined and easily identifiable chains of islands that are indicative of quasi-periodic orbits. These chains of islands surround fixed points, which indicate periodic orbits.
