DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GDEq/27/">Mo
 rse theory\, Bruhat cells and Unitriangular geometry</a>\nby Petr Pushkar 
 as part of Geometry of differential equations seminar\n\n\nAbstract\nStron
 g Morse function is a Morse function with pairwise different critical valu
 es. For such a function we construct a collection of numbers\, which is a 
 (smooth) topological invariant of the strong Morse function.\n\nAlgebraica
 lly our construction is a close relative of the construction of Bruhat cel
 ls and belongs to Unitriangular geometry. We will present a generalization
  of determinant of any linear map between finite dimensional vector spaces
 .\n\nTalk based on a joint work with Misha Temkin.\n
