The Euler Characteristic of the Fiber Product of Morse Functions on Grassmannians

International Journal of Mathematics and Mathematical Sciences
For F=R, C, or H, let GkFn denote the Grassmannian of k-planes in Fn. For a well-known Morse function f:GkFn⟶R, we denote by Cf the fiber product of two copies of f. We prove a formula which describes χCf.

Effectless cut in the Laplace operator eigenvalue problem

Современная математика: Фундаментальные направления
This paper addresses the eigenvalue problem for the Laplace operator in a bounded planar domain. The general theory of compact self-adjoint operators implies that the spectrum of the problem is discrete and tends to infinity.
