- Spectral graph theory. Graph eigenvalues. Enumeration of walks. Matrix-Tree theorem. Connectivity and cuts. Random walks.
- Rings with polynomial identities via graphs. Amitsur-Levitski theorem. Weyl algebra. Capelli identities. Grassmann algebra.
- Eulerian tours. Enumeration in directed and undirected case, orientations. Interlace polynomials.
- Gessel-Viennot method. Determinants and Pfaffians.
- Tableaux, dual graphs, and symmetric functions.
- Introduction to Total Positivity.
