Adic Spaces I

March 21, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical

We will recall the definition and some properties of Huber rings and we will define and study spaces of continuous valuations.

Adic Spaces II: Examples

March 28, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical

We will explain in detail some examples of affinoid adic spaces including the unit ball (for rank 1 valuations). If time permits we will talk on completion and rational subsets.

Arithmetic Okounkov bodies I

April 4, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical
  • Tags: introductory, recurring

We will review the construction of Newton-Okounkov bodies by Kaveh-Khovanskii and Lazarsfeld-Mustata, within a general framework of semigroups and cones associated to filtrations.

Arithmetic Okounkov bodies II

April 18, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical
  • Tags: introductory, recurring

We will address the construction of arithmetic Newton-Okounkov bodies, and more generally functions on Newton-Okounkov bodies arising from filtrations, following ideas of Boucksom and collaborators.

Arithmetic Okounkov bodies III

April 25, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: Seminari Tropical
  • Tags: advanced, recurring

In the third talk we will continue the discussion of arithmetic Newton-Okounkov bodies and more.

Perfectoid spaces I

May 2, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical

Perfectoid spaces are specially interesting instances of adic spaces.

Positividad aritmética sobre variedades tóricas

May 9, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: Seminari Tropical

Espais àdics feixistes

May 16, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical

Estudiarem com definir un candidat a feix estructural per a un espai afinoide (de la forma Spa(A,A^+)) i en quins casos surt un feix.

What is…a Darmon point?

May 30, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
  • Categories: disseminate, Seminari Tropical

The theory of Heegner points, which form a supply of algebraic points on a given elliptic curve, are one of the main tools used in proving the known cases of the Birch and Swinnerton-Dyer conjecture.

Positividad aritmética sobre variedades tóricas II

June 20, 2017 10:00 – 11:00
  • Venue: Seminari C3B (C3B/158)
