SCHMüDGEN, K. - Unbounded Operator Algebras and Representation Theory - Operator Theory: Advances and Applications, 37

Boston: Birkhäuser, 1990. First Edition; First Impression. Hardcover. ISBN: 3764323213. Very minor shelf wear ONLY. ; Algebras of unbounded operators in Hilbert space naturally arise in unitary representation theory of Lie groups and quantum field theory. They appear as representations of Lie algebras or as field operator systems. While some foundational tools, such as the weak commutant, were introduced earlier, a systematic study began in the 1970s, led by Borchers, Lassner, Powers, Uhlmann, and Vasiliev. The theory connects with areas like von Neumann algebras, locally convex spaces, distribution theory, and noncommutative probability. ; 17.7 x 23.6 x 2.9 cm; 380 pages.
