We show that F is a weighted Jordan homomorphism provided that A is zero product determined and weakly amenable. These conditions are in particular fulfilled when A is the group algebra L1(G) with G any locally compact group. We also study a more general type of continuous linear maps F : A → B that satisfy F(a)F(b)+F(b)F(a) = 0 whenever ab = ba = 0. We show in particular that if F is surjective and A is a C∗-algebra, then F is a weighted Jordan homomorphism.}, organization = {Slovenian Research Agency - Slovenia P1-0288}, organization = {MCIU/AEI/FEDER Grant PGC2018-093794-B-I00}, organization = {Junta de Andalucia FQM-185 P20_00255 MIU FPU18/00419 EST19/00466}, organization = {Proyectos I+D+i del programa operativo FEDER-Andalucia Grant A-FQM-484-UGR18}, publisher = {Elsevier}, keywords = {Zero product determined Banach algebra}, keywords = {Weakly amenable Banach algebra}, keywords = {Group algebra of a locally compact group}, keywords = {C∗-algebra}, keywords = {Algebra of approximable operators}, keywords = {Weighted Jordan homomorphism}, keywords = {Two-sided zero products}, keywords = {Linear preserver}, title = {Maps preserving two-sided zero products on Banach algebras}, author = {Bresar, M. and Castillo Godoy, María Luisa and Villena Muñoz, Armando Reyes}, }
