COVID-19 has overshadowed all events throughout the world over the past two years, with the first reported case in Wuhan, China in Dec 2019. It was declared a pandemic by the WHO in March 2020.

## Talk on Semicontinuity for Families of Power Series and Applications to Singularity Invariants and Computational Algorithms

# Talk on Semicontinuity for Families of Power Series and Applications to Singularity Invariants and Computational Algorithms

Mon, Nov 22 2021 to Mon, Nov 22 2021

The Session will consist of three parts:

• A general semicontinuity theorem for families of modules defined by power series.

• Proof that the delta invariant in a family of parameterizations of reduced curve singularities is upper semicontinuous.

• A new algorithm for standard basis computations of 0-dimensional ideals in a power series ring that provides a significant speed up when coefficient swell occurs.

## J. Conway Spirited Seminar Series: Algebra and Topology of Lattices of Subgroups

# J. Conway Spirited Seminar Series: Algebra and Topology of Lattices of Subgroups

Mon, Nov 08 2021 to Mon, Nov 08 2021

It has long been known that the lattice of subgroups of a finite group determines whether the group is solvable. In this talk, Prof. Russ Woodroofe will overview how to recognise a solvable group from its subgroup lattice. He is particularly interested in a topological and/or commutative algebraic characterisation (the sequentially Cohen-Macaulay condition).**Date**: Monday, November 8, 2021**Time: **4:00 - 5:00 pm

The central topic of the school is the mutual interaction of algebra, combinatorics, and geometry. Objects of research in algebraic geometry are affine as well as projective varieties and their associated invariants which can be studied using methods from algebra and combinatorics. Toric and tropical varieties are instances where such kinds of approaches were and still are very successful. In discrete geometry cones, graphs, hyperplane arrangements and matroids are examples of research subjects that naturally play prominent roles in algebra and discrete mathematics.

The field of harmonic analysis aims to understand, qualitatively and quantitatively, the several types of oscillatory phenomena in nature. The Fourier transform (après the work of Jean-Baptiste Joseph Fourier 1768 - 1830) is one of the main mathematical tools for that. The field of analytic number theory, as the name suggests, uses tools from analysis to understand different types of problems in number theory.
