Paolo Ghiggini will give a seminar talk titled "A relative exact sequence for Lagrangian Floer homology"

**Abstract:** Some years ago Chantraine, Dimitroglou-Rizell, Golovko and I defined a

version of Lagrangian Floer homology for Lagrangian cobordisms also

known as Cthulhu homology. I will show that concatenation of cobordisms

induce a long exact sequence in Cthulhu homology. A similar exact

sequence was proved by Cieleibak and Oancea if the negative ends of the

cobordisms are filled.

This is a talk in our Geometry and Topology seminar series.
