Tropical ideals are combinatorial objects that abstract the behavior of the collections of subsets of lattice points that arise as the supports of all polynomials in an ideal. Their structure is governed by a sequence of ‘compatible’ matroids and, even though most tropical ideals are not realizable by an ideal of polynomials, they share many properties with usual ideals in a polynomial ring.
In this talk, I will introduce the notion of tropical ideals and discuss various works studying some of their properties and their possible associated (tropical) varieties. I will also share some results about the class of matroids that can be represented as the variety of a tropical ideal, and some recent developments in the study of a tropical Nullstellensatz.
