Einstein's equations in 4-dimensional Riemannian geometryI will begin by reviewing some of the features of Riemannian geometry that are particular to dimension 4 as well as what is known about compact Riemannian solutions to Einstein’s equations in 4-dimensions. Then I will outline a new way to write Einstein’s equations in 4-dimensions as a gauge theory, somewhat analogous to Maxwell’s equations and the electromagnetic potential. If there is time I hope to mention some open questions suggested by this new formalism. This “gauge theoretic approach” is joint work with Kirill Krasnov and Dmitri Panov.
O Seminário Informal de Geometria é, como o nome indica, um seminário informal para estudantes graduados e pós-doutrorandos no IST partilharem as suas ideias entre si e um bom local para colocar perguntas simples sem qualquer pressão.
