Erik Palmgren: A constructive examination of a Russell style ramified type theory

The lecture was held within the framework of the Hausdorff Trimester Program: Types, Sets and Constructions. Abstract: In this talk we examine the natural interpretation of a ramified type hierarchy into Martin-Löf type theory with an infinite sequence of universes. It is shown that unde

Marc Levine: Chow Witt groups, ramification and quadratic forms

The lecture was held within the framework of the Hausdorff Trimester Program: Periods in Number Theory, Algebraic Geometry and Physics. Abstract: Replacing the Chow groups with the Barge-Morel-Fasel Chow-Witt groups enables refining many classical constructions involving algebraic cycles

Multivariable Calculus | What is a vector field.

We introduce the notion of a vector field and give some graphical examples. We also define a conservative vector field with examples. http://www.michael-penn.net http://www.randolphcollege.edu/mathematics/

On the decidability of ℚªᵇ_p - J. Koenigsmann - Workshop 2 - CEB T1 2018

Jochen Koenigsmann (Oxford) / 05.03.2018 On the decidability of ℚªᵇ_p I will propose an effective axiomatization for ℚªᵇ_p, the maximal abelian extension of the p-adics, and present a strategy for proving quantifier elimination (in a variant of the Macintyre language) for the theory thus

Pushing back the barrier of imperfection - F-V. Kuhlmann - Workshop 2 - CEB T1 2018

Franz-Viktor Kuhlmann (Szczecin) / 06.03.2018 The word “imperfection” in our title not only refers to fields that are not perfect, but also to the defect of valued field extensions. The latter is not necessarily directly connected with imperfect fields but may always appear when at least

Padma Srinivasan - Conductors and minimal discriminants of hyperelliptic curves - AGONIZE conference

Conductors and minimal discriminants are two measures of degeneracy of the singular fiber in a family of hyperelliptic curves. In genus one, the Ogg–Saito formula shows that these two invariants are equal, and in genus two, Qing Liu showed that they are related by an inequality. In this ta
