Query: On equivariant dendriform algebras   Dendriform algebras are certain associative algebras whose product splits
into two binary operations and the associativity splits into three new
identities. In this paper, we study finite group actions on dendriform
algebras. We define equivariant cohomology for dendriform algebras equipped
with finite group actions similar to the Bredon cohomology for topological
$G$-spaces. We show that equivariant cohomology of such dendriform algebras
controls equivariant one-parameter formal deformations.
