Dirichlet eigenvalue problem

Dirichlet eigenvalue problem --- проблема Дирихле о собственных значениях.

The Dirichlet eigenvalue problem can be introduced by restricting the eigenfunctions of the graph Laplacian to [math]\displaystyle{ f }[/math] such that [math]\displaystyle{ f(u_{0}) = 0 }[/math] for all boundary vertices [math]\displaystyle{ u_{0} \in \partial V }[/math].
