Structure theorems for both the resolvent and the heat kernel of b-pseudodifferential operators on a compact manifold with corners (of arbitrary codimension) are presented. In both cases, the kernels are realized as classical conormal functions on appropriate manifolds with corners. To prove these results, a space of operators with complex parameter (or tempered operators) is introduced. These ...

The norm resolvent convergence of discrete Schrödinger operators to a continuum operator in the limit is proved under relatively weak assumptions. This result implies, particular, spectrum with respect Hausdorff distance.

We construct an analogue of Kontsevich and Vishik’s canonical trace for a class of pseudodifferential boundary value problems in Boutet de Monvel’s calculus on compact manifolds with boundary. For an operator A in the calculus (of class zero), and an auxiliary operator B, formed of the Dirichlet realization of a strongly elliptic second-order differential operator and an elliptic operator on th...

It was shown in [2] that if T is a contraction in a Hilbert space with finite defect (‖T‖ ≤ 1, rank(I−T ∗T ) <∞), and its spectrum σ(T ) doesn’t coincide with the closed unit disk D, then the following Linear Resolvent Growth condition ‖(λI − T )−1‖ ≤ C dist(λ, σ(T )) , λ ∈ C\σ(T ), implies that T is similar to a normal operator. The condition rank(I − T ∗T ) < ∞ characterizes how close is T to...

In this paper, we introduce and study a system of mixed variational-like inclusions and a system of proximal operator equations in Banach spaces which contains variational inequalities, variational inclusions, resolvent equations, system of variational inequalities and system of variational inclusions in the literature as special cases. It is established that the system of mixed variational-lik...
