27.1. - 30.1.2025: CaLiForNIA kick-off conference PDF Print

CaLiForNIA kick-off conference

Time: Monday, 27 January - Thursday, 30 January, 2025

Venue: Brno, Czech Republic, hotel Continental

Since 2024, we are proudly part of one of the Brussels financed doctoral networks. Now, all 11 doctoral students (two of them with us in Brno) are on board and the Masaryk University is hosting the kick-off meeting of the project.

The programme collects the introductory lectures of all 11 supervisors, some more contributed talks, and further activities (including the exhibition Women in Mathematics from around the world. A gallery of portraits - https://womeninmath.net/).

The details will be updated on the conference pages: https://conference.math.muni.cz/california-msca/.

Here is the preliminary list of the lectures of all supervisors (programme in PDF):

  • E. Bekkers: Group equivariant graph neural networks
  • R. Ó Buachalla: Noncommutative geometry and quantum groups
  • A. Cattaneo: Palatini Cartan gravity
  • E. Ercolessi: Geometry of quantum states for efficient quantum computation
  • R. Fioresi: Sheaf theory and information geometry in understanding parameter and data spaces in group equivariant graph neural networks
  • E. Latini: Holography and conformal YM equation
  • M.A. Lledo: Continuous spin representation of the Poincaré group
  • K. Neusser: Rigid geometric structures and Cartan connections
  • A. Perez-Canelas: Quantum Simulations
  • J. Slovák: Tractor calculus views towards the geometric control theory problems
  • K. Strung: C*-algebra models for quantum spaces


Everybody is welcome to join the zoom meetings with all the lectures: https://cesnet.zoom.us/j/91825173477?pwd=G3S8TTbLPkY2yqZtNSZCFoBpwLtDjM.1 (or come to the individual talks in the hotel Continental meeting room).

48th mathematical hike - Saturday, December 21, 2024 PDF Print

Dear friends of hikes and mathematics,

you are cordially invited to the 48th mathematical hike planned on Saturday 21st of December. Meet at 9:18 at the "Anthropos" bus stop.

The hike is about 10 km long, we will go uphill towards the observation tower Holedná. We also invite you to our traditional mathematical carol-singing. (lyrics in czech, though)


Looking forward to see you,

Pavel Francírek and Jonatan Kolegar, organizers

MUNI Seminar series - Machine Learning in Banking & Finance - JOSEF TEICHMANN PDF Print

Mathematics, Physics & Computer Science Seminar Series

13 November 2024, 4:30 PM, Meeting room nr. 300, Komenského náměstí 220/2

JOSEF TEICHMANN

Machine Learning in Banking & Finance

We highlight on some showcases like Deep Hedging or Deep Simulation, where the arrival of novel machine learning technologies changed the landscape of modeling in Banking & Finance. We also present fascinating mathematical developments from areas like stochastics, geometry or algebra which accompanied theses changes

 
47th mathematical hike - Saturday, November 9, 2024 PDF Print

Dear friends of hikes and mathematics,

you are cordially invited to the 47th mathematical hike planned on Saturday, November 9. Start at 8:44 at the train station Doubravice nad Svitavou. (train from Brno main station leaves at 8:00).

The planned route is no shorter than 12 km and no longer than 17 km and goes through the nearby forests, ending at one of the nearby train stations.

A short explanation: we organize these hikes for mathematicians (and their friends), so it is not a mathematical activity, but a time together outdoors. You can read about past hikes in the chronicle.

Have a nice autumn and we look forward to seeing you,

Pavel Francírek and Jonatan Kolegar, organizers

Abstract: Simplicial techniques are important in homotopy theory and (higher) category theory. They are also important in type theory, because they were used by Voevodsky to construct a new model of type theory. This model validates principles like the Univalence Axiom and Higher-Inductive Types, leading to a new form of type theory, which goes by the name of Homotopy Type Theory. This model construction uses a fundamental result about simplicial sets: that it carries a Quillen model structure in which the fibrations are the Kan fibrations.

It turns out that the standard proofs of the existence of the model structure as well as the model of homotopy type theory use non-constructive principles; however, in this series of lectures I want to outline an approach that aims to give a constructive account of these results. For this, a key ingredient is the theory of algebraic weak factorisation systems, as developed by Garner, Riehl, Bourke and others; this theory is used to formulate a more explicit variant of the traditional Kan fibrations: the effective Kan fibrations, as introduced by Faber and myself. I will explain these notions and indicate how far we are in giving constructive and explicit proofs of the fundamental results in simplicial homotopy theory. I will also explain the relation to other approaches, in particular one due to Henry and Gambino.

This series of lectures will be accessible to an audience of PhD students and researchers in Mathematics with a basic training in category theory.
