Consider a bipartite graph G = (V,E) with parts N and M as shown in Figure 1. The function f(A) = |NG(A)| for A ⊆ N , where NG(A) is the neighborhood of set A, is a submodular function. A practical example is adding sensors to observe an area. Adding a new sensor will either cover an entirely new area, or overlap with area that is already covered. For sensor subsets A and B with A ⊆ B, the new ...

Speaker: Gregory Arone (Virginia) Title: Part 1: operads, modules and the chain rule Abstract: Let F be a homotopy functor between the categories of pointed topological spaces or spectra. By the work of Goodwillie, the derivatives of F form a symmetric sequence of spectra ∂∗F . This symmetric sequence determines the homogeneous layers in the Taylor tower of F , but not the extensions in the tow...
