An Additional Remark on Self-conjugate Functions of Boolean Algebras
In this note I add several remarks to my paper . Let / be a self-conjugate function on a Boolean algebra, in [l] it was shown that if fn= id and f Φ id, then n is even and/2 = id. Necessary and sufficient conditions for a self-conjugate function / to have the property/2 = /were given. Here we extend results of this type. The references in the proofs are from .
