摘要
A projection on a complex Banach space is bicircular if its linear combinations with the complementary projection having coefficients of modulus one are isometrics. Such projections are always bicontractive. In this paper we prove structure theorems for bicircular projections acting on the spaces of the full operator algebra, symmetric operators and antisymmetric operators.
