1. In t roduc t ion . A unitary polarity of a finite projective plane 8P of order q is a polarity 0 having q + 1 absolute points and such that each nonabsolute line contains precisely q + 1 absolute points. Let G{6) be the group of collineations of SP centralizing 6. In [15] and [16], A. Hoffer considered restrictions on G (6) which force SP to be desarguesian. The present paper is a continuati...

A well-known result of Posner’s second theorem states that if the commutator each element in a prime ring and its image under nonzero derivation are central, then is commutative. In present paper, we extended this bluestocking to an arbitrary with involution involving ideals. Further, apart from proving several other interesting exciting results, established ∗-version Vukman’s theorem. Precisel...
