Sz. Yan et al., GROUPOID STRUCTURE OF TOEPLITZ ALGEBRA OVER L-SHAPED DOMAIN, Science in China. Series A, Mathematics, Physics, Astronomy & Technological Sciences, 40(2), 1997, pp. 163-171
The structure of the groupoid G associated with the Toeplitz C-algebr
a C(Omega) of the L-shaped domain is discussed. The detailed characte
rization of M infinity by the classification of the closed subgroup of
the Euclidean space is presented.
