Charting the operator terrain
by ERNEST, John
fromMemoirs of the American Mathematical Society
The purpose of this memoir is to offer a cartographic procedure for bringing some organizational sense to the prodigious task of exploring and describing the vast and varied terrain of bounded operators on a separable Hilbert space. While we prove (in a certain sense) that the c…
This work deals with the general theory, both linear and non-linear, of operator semigroup product formulas of the type lim [over] n[right arrow][infinity] F(t/n) [superscript]n = G(t). The principal application is the use of the Trotter-Lie product formula e [superscript]tC = l…
This paper investigates algebraic and topological aspects of the study of reflexive operator algebras.
The inverse problem of the calculus of variations is examined from an operator-theoretic point of view instead of as an integration problem. These operators give a convenient, presentation of generalizations to higher order Lagrangians. Original material on this subject will be …
