Involutions on finite-dimensional algebras over real closed fields
Published online by Cambridge University Press: 09 April 2009
Abstract
It is shown that the following conditions on a finite-dimensional algebra A over a real closed field or an algebraically closed field of characteristic zero are equivalent: (i) A admits a special involution, in the sense of Easdown and Munn, (ii) A admits a proper involution, (iii) A is semisimple.
