°Õ¾±³Ù±ô±ð:ÌýInfinite matroids on lattices

´¡²ú²õ³Ù°ù²¹³¦³Ù:ÌýThere are at least two well-studied ways to extend matroids to more general objects - one can allow the ground set to be infinite, or instead define the concept of independence on a lattice other than a set lattice. I will discuss some nice ideas that arise when combining these two generalizations. This is joint work with Andrew Fulcher.
