Which self-maps appear as lattice anti-endomorphisms?
Stephan Foldes, Jeno Szigeti
Let f be a self-map of the set A. We give a necessary and sufficient condition for the existence of a lattice structure on A such that f becomes a lattice anti-endomorphism with re…

A new class of supermatrix algebras defined by transitive matrices
Jeno Szigeti
We give a natural definition for the transitivity of a matrix. Using an endomorphism d of a base ring R and a transitive nxn matrix over the center Z(R), we construct the subalgebr…
