Mathematical Conversations

A magnetic interpretation of the nodal count on graphs
6:00pm|Birch Garden, Simons Hall

The study of nodal sets, i.e. zero sets of eigenfunctions, on geometric objects can be traced back to De Vinci, Galileo, Hook, and Chladni. Today it is a central subject of spectral geometry. Sturm (1836) showed that in 1D, the $n$-th eigenfunction...
