Algebraic $$K$$-theory invariants for operator theory. (English) Zbl 0831.46080
Curto, Raúl E. (ed.) et al., Multivariable operator theory. A joint summer research conference on multivariable operator theory, July 10-18, 1993, University of Washington, Seattle, WA, USA. Providence, RI: American Mathematical Society. Contemp. Math. 185, 187-194 (1995).
Summary: We present a modern version of an invariant first introduced by L. G. Brown in his study of the universal coefficient theorem for $$\text{Ext}(X)$$ [Bull. Am. Math. Soc. 81, 1119-1121 (1975; Zbl 0332.46038)].
