Introduction to B-theory

B-Theory: Lecture & Eastern seminar 15


Introduction to introduction to B-theory 15

Topics of the week.
This week we continue description of the equivariant cohomology and cohomology of the algebraic quotients.
In particular we will consider Mathai-Quillen type representations (following Moore-Nekrasov-Shatashvili) and
QFT cases (in the spirit of Losev-Nekrasov-Shatashvili). We will pay some attention to phenomenon of freckles
(we will consider both philosophical and computational aspects of this phenomena).
The topics of this week may be considered as a natural introduction to Shifman-Yung vortex strings and discussion of
Losev-Shifman-Yung conjecture of the new type of little string theory.
In order to discuss all aspects of LSY conjecture I will discuss little string construction later in the course.
