35 p, 433.4 KB Resultant and conductor of geometrically semi-stable self maps of the projective line over a number field or function field / Szpiro, Lucien (CUNY Graduate Center (Nova York, Estats Units d'Amèrica)) ; Tepper, Michael (Penn State Abington. Division of Science and Engineering (Abington, Estats Units d'Amèrica)) ; Williams, Phillip (The King's College (Nova York, Estats Units d'Amèrica))
We study the minimal resultant divisor of self-maps of the projective line over a number field or a function field and its relation to the conductor. The guiding focus is the exploration of a dynamical analog to Theorem 1. [...]

36 p, 474.0 KB Entropy and flatness in local algebraic dynamics / Majidi-Zolbanin, Mahdi ; Miasnikov, Nikita ; Szpiro, Lucien
For a local endomorphism of a noetherian local ring we introduce a notion of entropy, along with two other asymptotic invariants. We use this notion of entropy to extend numerical conditions in Kunz' regularity criterion to every contracting endomorphism of a noetherian local ring, and to give a characteristic-free interpretation of the definition of Hilbert-Kunz multiplicity. [...]
