К первой паре / Algebra. Lecture 2. Adjoint classes, the Lagrange theorem and normal subgroups

Vyshka Online continues the course of recorded lectures on algebra in conjunction with the undergraduate program Applied Data Analysis at the National Research University Higher School of Economics.

In the second class, Dmitry Trushin explains what are left and right adjacent classes on subgroups, what consequences follow from the Lagrange theorem, and what factor groups on a normal subgroup are needed for.
