Zeta functions of elliptic cone operators
, 2011 . This paper is an overview of aspects of the singularities of the zeta function, equivalently, of the small time asymptotics of the trace of the heat semigroup, of elliptic cone operators.

In this article, we investigate the essential pseudospectra through the framework of polynomially inessential operators, which extends the class of polynomially strictly singular operators and provides a broader setting for Fredholm-type ...

Random Schrödinger operators arising from lattice gauge fields II: determinants
, 1995 We introduce and study the variational problem to maximize the determinant of a random selfadjoint operators obtained from discrete abelian or nonabelian lattice gauge fields.

Pseudospectra of the Wave Operator with an Absorbing Boundary
, 1993 For systems which can be described by u t = Au, with a highly non-normal matrix or operator A, the spectrum of A may describe the behavior of the system poorly.

Linear maps preserving the generalized spectrum
, 2007 : Let H be an infinite-dimensional separable complex Hilbert space and B(H) the algebra of all bounded linear operators on H. For an operator T in B(H), let σg(T) denote the generalized spectrum of T.
