It's very difficult for me to find any simple literature to explain this idea.
J[itex]\in[/itex]Mn(ℂ) is a coninvolutory (or a "coninvolution") if A-1=[itex]\overline{A}[/itex]
I'm looking to prove this lemma:
Let A be an element of Mn(ℂ) and A is nonsingular, then [itex]\bar{A}[/itex]-1A is coninvolutory.
I see that the identity matrix is a coninvolution. Does anyone have another example?
