Let R be a prime ring with involution of the first kind, and characteristic / 2, 3. Let K denote the skew elements of R, and let C denote the extended centroid of Ε½ . R . Assume that RC : C / 1, 4, 16. It is shown that any Lie derivation of K into Β² : itself can be extended to an ordinary derivation
## dedicated to helmut wielandt on the occasion of his 90th birthday Let H be a finite group having center Z H of even order. By the classical Brauer-Fowler theorem there can be only finitely many non-isomorphic simple groups G which contain a 2-central involution t for which C G t βΌ = H. In this
