DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ENAAS/155/">
 Automatic additivity of multiplicative and Jordan multiplicative maps</a>\
 nby Mateo Tomašević (University of Zagreb\, Croatia) as part of European
  Non-Associative Algebra Seminar\n\n\nAbstract\nIn this talk\, we discuss 
 the problem of automatic additivity for multiplicative maps between rings\
 , following the classical results of Martindale and Jodeit-Lam. We present
  a complete description of Jordan multiplicative self-maps on full matrix 
 algebras M_n(F)\, where F is a field of characteristic not equal to 2. Wit
 hout imposing additional assumptions\, we show that such maps are either c
 onstant (and equal to a fixed idempotent)\, or additive (and hence Jordan 
 monomorphisms). This result is joint work with Ilja Gogić.\n
