Split exact sequence

In mathematics, a split exact sequence is a short exact sequence in which the middle term is built out of the two outer terms in the simplest possible way. (Wikipedia).

Yonatan Harpaz - New perspectives in hermitian K-theory II

Warning: around 32:30 in the video, in the slide entitled "Karoubi's conjecture", a small mistake was made - in the third bulleted item the genuine quadratic structure appearing should be the genuine symmetric one (so both the green and red instances of the superscript gq should be gs), an

Group Cohomology: Deformation Obstruction Theory For Groups

There is a general theme: H^2 = obstructions H^1 = deformations This is another one of these things. An H^2(G,A) extension is the obstruction to splittings of an exact sequence in groups, H^1(G,A) is the torsor of those splittings provided they exist. This is a sort of lazy review of this.
