Questions
In this mini-course, we'll review some of the common models for $(\infty,1)$-categories, then discuss the different ways that one can generalize them to obtain models for higher $(\infty,n)$-categories. We'll primarily consider simplicial models, whose generalizations can be obtained using multi-simplicial diagrams, $\Theta_n$-diagrams, and hybrids thereof. We'll also look at further variants via mixing and matching the discreteness and completeness conditions used to define Segal categories and complete Segal spaces, respectively, and which combinations actually lead to distinct models.

Questions
I will attempt to give a friendly introduction to the theory of $\infty$-operads, a powerful framework for working with homotopy-coherent algebraic structures. In the first talk I will introduce Lurie’s model of $\infty$-operads, and in the second I will survey some other models, including extensions to enriched $\infty$-operads.

Models for homotopical higher categories, Part II
In this mini-course, we'll review some of the common models for $(\infty,1)$-categories, then discuss the different ways that one can generalize them to obtain models for higher $(\infty,n)$-categories. We'll primarily consider simplicial models, whose generalizations can be obtained using multi-simplicial diagrams, $\Theta_n$-diagrams, and hybrids thereof. We'll also look at further variants via mixing and matching the discreteness and completeness conditions used to define Segal categories and complete Segal spaces, respectively, and which combinations actually lead to distinct models.

Introduction
Finite descent and the Lawrence--Venkatesh method
If Y is a curve of genus at least 2 over a number field, then the finite descent obstruction cuts out a subset of the adelic points, which is
conjecturally equal to the set of rational points. In particular, we expect this set to be finite. In this talk, I will present ongoing work with Jakob
Stix proving that certain projections of the finite descent locus are finite, as predicted by this conjecture. The method we employ can be
loosely described as "Lawrence--Venkatesh for Grothendieck's section set".

Algebraic spaces and Algebraic stacks
In this talk, after recalling the notion of a stack over an arbitrary site, I will introduce the notions of an algebraic space, an algebraic stack and a Deligne-Mumford stack. I will then introduce some examples and properties of these "generalized schemes".

Online: Buildings, quaternions and Drinfeld-Manin solutions of Yang-Baxter equations
To be useful in theoretical physics, mathematical structure has to be sufficiently rich and cover several fields of mathematics, physics and, potentially, computer science. One of the barriers to overcome is different languages and different terminologies. We will give a brief introduction to the theory of buildings and present their geometric, algebraic and arithmetic aspects. In particular, we present explicit constructions of infinite families of quaternionic cube complexes, covered by buildings. We will use these cube complexes to describe new infinite families of Drinfeld-Manin solutions of Yang-Baxter equations.
