1. On the space of symmetric operators with multiple ground states.

Author

Agrachev, A.

Subjects
*HOMOLOGY theory, *SYMMETRIC operators, *LINEAR operators, *SELFADJOINT operators, *EIGENVALUES
Abstract

We study the homology structure of the filtration of the space of self-adjoint operators by the multiplicity of the ground state. We consider only operators acting on a finite-dimensional complex or real Hilbert space, but infinite-dimensional generalizations are easy to guess. [ABSTRACT FROM AUTHOR]
