$$ -Jordan-type maps on $C^{}$ -algebras

Bruno Leonardo Macedo Ferreira, Bruno Tadeu Costa

Let $A$ and $A^{'}$ be two $C^{*}$ -algebras with identities $I_{A}$ and $I_{A^{'}}$ , respectively, and $P_{1}$ and $P_{2} = I_{A} - P_{1}$ …

C*-algebras of groupoid morphisms

Bruno Tadeu Costa, Renan Gambale Romano, Felipe Vieira

In this paper we suggest a definition for a C*-algebra attached to an injective morphism of some Étale groupoid. We take into account all the peculiarities of such objects and pres…

$$ -Lie-Jordan-type maps on $C^{}$ -algebras

Bruno Leonardo Macedo Ferreira, Bruno Tadeu Costa

Let A and A' be two Cstar-algebras with identities I_A and I_A', respectively, and P_1 and P_2 = I_A - P_1 nontrivial projections in A. In this paper we study the characterization…
