SUMMARY:Algebraic Graph Theory - Alan Lew
CLASS:PUBLIC
DESCRIPTION:TITLE: Eigenvalues of high dimensional Laplacian operators\n\nS
 PEAKER:\n Alan Lew\n\nAFFILIATION:\n Carnegie Melon University\n\nLOCATION
 :\n Please contact Sabrina Lato for Zoom link.\n\nABSTRACT: A simplicial
  complex is a topological space built by gluing\ntogether simple building 
 blocks (such as vertices\, edges\, triangles\nand their higher dimensional
  counterparts). Alternatively\, we can\ndefine a simplicial complex combin
 atorially\, as a family of finite\nsets that is closed under inclusion. In
  1944\, Eckmann introduced a\nclass of high dimensional Laplacian operator
 s acting on a simplicial\ncomplex. These operators generalize the Laplacia
 n matrix of a graph\n(which can be seen as a 0-dimensional Laplacian)\, an
 d are strongly\nrelated to the topology of the complex (and in particular\
 , to its\nhomology groups).
