• Resumen

  • It is shown that the following conditions on a finite-dimensional algebra over a real closed field or an algebraically closed field of characteristic zero are equivalent: (i) admits a special involution, in the sense of Easdown and Munn, (ii) admits a proper involution, (iii) is semisimple.
