Title: Critical sets of harmonic functions and Almgren's frequency functionAbstract: Given a harmonic function on a nice domain in n-dimensional Euclidean space, its critical set (the set of points where its gradient vanishes) is known to have dimension at most n-2, with locally finite (n-2)-dimensional Hausdorff measure. For harmonic polynomials, the Hausdorff measure can be […]

Title: Graphs embedded on surfaces and their delta-matroidsAbstract: By “cutting out” the edges and vertices of a graph cellularly embedded in a surface, we obtain a ribbon graph. A partial Petrial is obtained from a ribbon graph by selecting a subset of the ribbon edges and adding a half-twist to each. The resulting ribbon graph […]
