Characterizing derivations and anti-derivations on group algebras through orthogonality
Hoger Ghahramani
Let L^1(G) and M(G) be group algebra and measure algebra of a locally compact group G, respectively and D:L^1(G)-->M(G) be a continuous linear map. We consider D behaving like deri…

Left Ideal Preserving Maps on Triangular Algebras
Hoger Ghahramani
Let A be a unital algebra over a commutative unital ring R. We say that A is a SLIP algebra if every R-linear map on A that leaves invariant every left ideal of A is a left multipl…
