Relativistic physics II

NTMF038

prof. RNDr. Jiří Bičák, DrSc., dr.h.c.,    doc. RNDr. Oldřich Semerák, DSc.

spring term 2021, 4/2 exam/credit

Short syllabus:

Lagrangian formalism and conservation laws in GR. 3+1 splitting of space-time, Gauss-Codazzi equations. Initial (Cauchy) problem in GR. Hamiltonian formalism (in scalar-field theory, in electrodynamics, and) in GR. Concepts of causal structure (different "levels of predictability"). Geometry of time-like and null congruences, Frobenius theorem. Relativistic strings.

A follow-up of the course NTMF037 – Relativistic physics  I (in fall term).
Mainly suitable as a master course for theoretical physicists.

Time, space, rules:

Monday 9:50-12:05 and 13:10-15:25, presently taught in English via the Zoom application.

Lectures will be recorded, videos will be added gradually at the bottom of this page. If you noticed anything we should delete from the recordings, please tell us.
Organization will be the same as in previous term, with student talks delivered as web presentations. One talk per year (per 2 semesters of Relativistic physics) is generally required for credit.
Feedback via email (oldrich.semerak@mff.cuni.cz) is welcome.
Examination in Czech as well as in English may be chosen.
