Boundary representations of operator spaces, and compact rectangular matrix convex sets
Journal of operator theory, 2016We initiate the study of matrix convexity for operator spaces. We define the notion of compact rectangular matrix convex set, and prove the natural analogs of the Krein--Milman and the bipolar theorems in this context.

Compact Operators. Equations with Compact Operators
1996In this chapter, we study an important class of linear continuous operators, namely, compact (or completely continuous) operators. On the one hand, compact operators are interesting because they inherit many properties of operators in finite-dimensional spaces.

Compact scheme for fractional diffusion-wave equation with spatial variable coefficient and delays
Applicable Analysis, 2020In this paper, we study the spatial variable coefficient fractional convection–diffusion wave equation with the singe delay and multi-delay numerically when the exact solution satisfies a certain regularity.

Dynamic Mode Decomposition for Continuous Time Systems with the Liouville Operator
Journal of nonlinear science, 2019Dynamic mode decomposition (DMD) has become synonymous with the Koopman operator, where continuous time dynamics are discretized and examined using Koopman (i.e. composition) operators.

Abstract We begin this part on spectral theory with a chapter on compact operators. These operators provide the abstract framework to treat integral equations. As was shown by F. Riesz, their spectral behavior is similar to that of operators on finite dimensional spaces.

Compact automorphism groups of vertex operator algebras
, 1996Let V be a simple vertex operator algebra which admits the continuous, faithful action of a compact Lie group G of automorphisms. We establish a Schur-Weyl type duality between the unitary, irreducible modules for G and the irreducible modules for V G ...

On Reflexive Compact Operators
Canadian Journal of Mathematics, 1977Let A be a compact operator on a separable Hilbert space . The aim of this paper is to investigate the relationship between the weak closure of the algebra of polynomials in A (denoted by U(A)) and its invariant subspace lattice Lat A.
