Radoslaw Kycia:
The Poincare lemma, antiexact forms, and fermionic quantum harmonic oscillator
Abstract:
I will present the connection between Poincare lemma and homotopy operator defined by Edelen. This will be used to determine functional calculus (Bittner’s operator calculus), which, in the case of a homotopy operator, resembles quantum fermionic oscillator algebra.
I will also present a topological/chain complex version of a homotopy operator.
Finally, I will show how this operator calculus looks in the setup of complex manifolds and how it ‘interacts’ with the Dolbeault complex.

Finitary functors
Abstract: Every finitary functor F between locally finitely presentable categories is finitely bounded, i.e., finitely generated subobjects of each FX factorize through the image (under F) of finitely generated subobjects of X. Conversely, finitely bounded functors preserving monomorphisms are finitary. We discuss conditions under which 'finitary = finitely bounded' holds for a l l functors. This is true e.g. for atomic Grothedieck toposes with finitely many finitely presentable atoms. We also study the finitely presentable objects in the categories [Set,Set]_fin of all finitary set functors and Mnd_fin(Set) of all finitary monads over Set.

MUNI Seminar series  Dana Stewart Scott  Enumeration Operators, Probability, Type Theory 


October 10, 2019 from 4:30 PM at Refectory of Augustinian Abbey at Mendel Square  Mendel Museum
Enumeration Operators, Probability, Type Theory
Abstract:
For a long time it has been known that enumeration operators on the powerset of the integers form a model of the λcalculus. More recently, the speaker realized that wellknown methods allow for the adjunction of random variables to the model. Also other wellknown ideas can expend the basic model into a model for MartinLöf type theory. Some recent work with a group of collaborators combines the two approaches by invoking Booleanvalued models. The talk will address the question of how to give this natural modeling interesting applications.
