摘要

Let AA be a Banach algebra. The flip on AA\opA \otimes A^\op is defined through AA\opa\tensorbb\tensoraA \otimes A^\op \ni a \tensor b \mapsto b \tensor a. If AA is ultraprime, \El(A)\El(A), the algebra of all elementary operators on AA, can be algebraically identified with AA\opA \otimes A^\op, so that the flip is well defined on \El(\A)\El(\A). We show that the flip on \El(A)\El(A) is discontinuous if A=K(E)A = K(E) for a reflexive Banach space EE with the approximation property.
