Jerusalem - Be'er Sheva Algebraic Geometry Seminar

Coleman and Vologodsky integration, height pairings and rational points

Dec 2, 16:00—17:00, 2020,

Speaker

Amnon Besser (Be'er Sheva)

Abstract

Coleman and Vologodsky integration are two related p-adic integration theories. In the first part of the talk I will explain the relation between the theories in some 1-dimensional cases discovered jointly with Sarah Zerbes, and I will conjecture on how this can be generalized, using in part the theory of averages on torsors for unipotent groups developed by Amnon Yekutieli.

In the second part of the talk I will give a new development of the theory of p-adic heights on Abelian varieties, which is in progress with Jan Steffen Muller and Padmavathi Srinivasan. I will explain how the Vologodsky theory gives us a way of computing local contribution to the pairing at each prime and not just at p. Time permitting I will explain the application to rational points, also in the joint work with Steffen and Padma.

אשנב למתמטיקה

העתקות פולינומיאליות ולוגיקה

Dec 8, 16:10—17:30, 2020, מרשתת

Speaker

מנחם קוג'מן

Abstract

באשנב נדבר על מאמר של Walter Rudin, בו הוא מציע הוכחה קצרה למשפט אקס: העתקה פולינומיאלית חח״ע מהמרוכבים בחזקת $n$ למרוכבים בחזקת $n$ היא על. נציג הוכחה המבוססת על משפט הקומפקטיות מלוגיקה ושלמות של מערכות אקסיומות. תוכלו להחליט בסוף האשנב איזו משתי ההוכחות קצרה יותר, או לא להחליט.
