Query: Some Topics in coalgebra calculus   We study a coderivation from a cobimodule into a coalgebra. Vector cofields
are defined by the action of a codual bicomodule on a coalgebra. This action is
induced by a codifferential. A construction of a codual object in the category
of bicomodules over a given coalgebra has been proposed. Various notions of
duality have been analysed in this context.
