    Ear decompositions of graphs$\colon$ an unexpected tool in Combinatorial Commutative Algebra
    Abstract(Click to expand) Ear decomposition is a classical notion in Graph Theory. It has been shown in [1, 2] that this notion can be used to solve difficult problems on homological properties of edge ideals in Combinatorial Commutative Algebra. This talk presents the main combinatorial ideas behind these results.
