Motivated by the notion of coaction of weak bialgebras on coalgebras, in this work the definition of coaction of weak Hopf algebras on coalgebras is introduced and several examples are presented. Furhtermore, the conditions on the weak smash coproduct are established in order to construct a weak Hopf algebra.

Joint work with Eneilson Fontes (Universidade Federal do Rio Grande, Brazil) and Grasiela Martini (Universidade Federal do Rio Grande, Brazil).
