Tóm tắt: The notion of F-thresholds of an ideal in a ring of prime characteristic was introduced by Huneke, Mustata, Takagi and Watanabe as a prime characteristic invariant of singularities. In this talk we will discuss the notion of F-thresholds of filtrations of ideals, its existence, and effective upper bounds. Moreover, we will see a connection between F-thresholds of symbolic power of filtrations and symbolic F-splitting, a new notion of singularity in prime characteristic introduced recently. This is a joint work with Dr. Arvind Kumar.
