In 2015, Chantraine, Dimitroglou-Rizell, Ghiggini and Golovko [CDRGG] have defined a Floer complex associated to a pair of Lagrangian cobordisms between Legendrian submanifolds. In this talk, I will explain how to construct a product structure on it. This product recovers the cup product on singular cohomology when we consider a Lagrangian filling of a Legendrian. Moreover, we show that this product is mapped to the product on Legendrian contact cohomology by a quasi-isomorphism from the Floer complex to the Legendrian contact cohomology complex defined in [CDRGG]. Finally, we can define higher order maps to extend the product (resp. the quasi-isomorphism) to A-infinity composition maps (resp. A-infinity functor).
