Orateur(s) Hugo Mariano - Université de Sao Paulo, Brésil,
Titre Multirings and applications to algebraic theory of quadratic forms, II
Horaire14:00 à 15:45

(Joint work with Kaique M.A. Roberto (IME-USP) and Hugo R.O. Ribeiro (IME-USP))
In the first talk of this series, we have presented the concept of multiring and showed how it can (functorially) encode the abstract theories of quadratic forms of special groups and real semigroups.  In this second talk, we present other notions of multirings R (as hyperbolic multirings and quadratic multirings) and pairs (R,T), where R is a multiring and T is a certain multiplicative subset (as DM-multirings, DP-multirings and quadratic pairs), that seem relevant to algebraic theory of quadratic forms.
