We obtain a characterization of bijective linear maps f : M n ( C ) → M n ( C ) satisfying f ( A ) f ( B ) = M whenever A B = N , where M and N are fixed n × n matrices.

Let ϕ be a bijective linear map on the algebra of n × n complex matrices such that ϕ ( e 12 ) = e 12 and [ ϕ ( A ) , ϕ ( B ) ] = e 12 whenever [ A , B ] = e 12 . The purpose of this paper is to describe ϕ. Surprisingly, ϕ has a different descr

In this paper, we describe linear maps between complex Banach algebras that preserve products equal to fixed elements. This generalizes some important special cases where the fixed elements are the zero or identity element. First we show that if such

Bijective linear maps preserving Lie products equal to rank-one nilpotents were recently shown to have nonstandard descriptions. In this paper, we show that bijective linear maps preserving Lie pro...

We characterize bijective linear maps on [Formula: see text] that preserve the square roots of an idempotent matrix (of any rank). Every such map can be presented as a direct sum of a map preserving involutions and a map preserving square-zero matric
