7th Seminar on Gravitational Waves and Numerical Relativity
Date: Oct. 15 (Tue.), 2019, 2 pm - 5 pm
Venue: Room #521, Buliding #56, SNU
Title: 1+3 formalism
Speaker: Chan Park (SNU)
Abstract: General relativity is a covariant theory that does not favor a coordinate or basis. However, its actual measurements and interpretations require the introduction of some local coordinate or basis. In particular, when timelike congruence is given in the spacetime, 1+3 formalism provides systematic way of splitting time and space. We reconstruct the 1+3 formalism by introducing a connection adapted to the conguence. Its application to the relativistic fluid will be discussed.
