F-singularities and F-jumping numbers | Pretalk |
| October 2nd | Wenliang Zhang University of Michigan |
F-jumping coefficients of principal ideals | We will prove that, in an excellent regular local ring of positive characteristic, all F-jumping coefficients of any principal ideal are rational and they form a discrete subset of the set of real numbers. |
| October 9th | Emily Witt University of Michigan |

| October 16th | Florian Enescu Georgia State University |
Anti-nilpotent modules and primary decomposition with respect to Frobenius | The talk will present the notion of anti-nilpotent modules and discuss ways of developing a primary decomposition theory for modules with Frobenius action over a ring of prime characteristic. Part of the work is joint with M. Hochster. |
| October 23rd | Dale Cutkosky University of Missouri |
Asymptotic growth of algebras associated to powers of ideals | I will talk on some of the results in my recent paper on finite generation of algebras associated to powers of ideals with Juergen Herzog and Hema Srinivasan. |

Gorenstein presentations and semidualizing modules | A famous result of Foxby, Reiten and Sharp says that a Cohen-Macaulay local ring admits a dualizing module if and only if it is a homomorphic image of a Gorenstein ring. We augment this result by showing that such a ring admits a nontrivial semidualizing module if and only if it admits a Gorenstein presentation Q/I such that the ideal I has a nontrivial decomposition. This is joint work with David Jorgensen and Graham Leuschke. |

Some Results on Finite Phantom Projective Dimension | I will sketch counterexamples to two conjectures posed by Aberbach-Hochster about localizing and taking direct summands of a module of finite phantom projective dimension. These will be among main results of my PhD thesis. |
| December 11th | Not meeting this week | Happy winter break! |
