Let H denote a finite-dimensional Hopf algebra with antipode S over a field β«ήβ¬ -. w We give a new proof of the fact, due to Oberst and Schneider Manuscripta Math. 8 Ε½ . x 1973 , 217α241 , that H is a symmetric algebra if and only if H is unimodular and S 2 is inner. If H is involutory and not sem

We prove that if A is a non-associative algebra over the field of real numbers, if 5 5 5 5 5 5 5 5 there is a norm ΠΈ on A satisfying xy s x y for all x, y in A, and if every one-generated subalgebra of A is finite-dimensional, then A is finite-dimensional.
