Operator Approximant Problems Arising from Quantum Theory

This book offers an account of a number of aspects of operator theory, mainly developed since the 1980s, whose problems have their roots in quantum theory. The research presented is in non-commutative operator approximation theory or, to use Halmos' terminology, in operator approximants.

Aceasta carte ofera o descriere a mai multor aspecte ale teoriei operatorilor, dezvoltate in principal din anii 1980, ale caror probleme isi au radacinile in teoria cuantica. Cercetarea prezentata este in teorie de aproximare a operatorilor necomutativi sau, pentru a utiliza terminologia lui Halmos, in aproximanti de operator.
