A Woman Has Won the ‘Nobel Prize of Math’ for the First Time Ever On Tuesday, one of the most prestigious mathematics prizes in the world was awarded to a woman for the first time. Karen Uhlenbeck, a mathematician and emeritus professor at the University of Texas at Austin, is now the first woman to win the Abel Prize for mathematics.The prize, according to New ....

Professor Chris McCord gave a beautifully eloquent tribute to our very own Anton Zettl for receiving the CLAS Distinguished Award👏🏻👏🏻👏🏻So wonderful to have one of our NIU mathematicians honored this year🎓🏆

Title : The Drinfeld Double and Modular Tensor Categories

The Drinfeld Double construction takes a finite dimensional Hopf algebra and returns a "quasitriangular" Hopf algebra that satisfies certain physics equations from statistical mechanics. If we perform that construction on the group algebra kG of a finite group, we get an object whose modules can be defined from the data of G.
We will also see that this "quasitriangular" property induces a representation of the modular group SL(2, Z).

Title and abstract below. Just between us, I anticipate seeing a large number of homology and cohomology groups of complex projective varieties. Have a look at Thm 3.43 on page 254 of Hatcher to get a sense of one ingredient of the story. (Taking R to be the ring of integers in that statement makes [M] into an element of just the sort of homology groups that have appeared in 720.) -MG

Title: On the Weak Lefschetz Principle in birational geometry.

Abstract: In this talk we will discuss the weak Lefschetz Principle in the context of birational geometry.

Our departing point will be the influential work of Solomon Lefschetz started in 1924. We will look at the original formulation of the Lefschetz hyperplane theorem in algebraic topology and build up to recent developments of it in birational geometry. In doing so, the slogan of the talk will be the following: there are many scenarios in geometry in which analogous versions of the Lefschetz hyperplane theorem hold. Such scenarios are somewhat unexpected and have had a profound impact in mathematics.

No prior familiarity with birational geometry will be assumed and the talk should be intelligible to graduate students and researchers outside of algebraic geometry.

35th Annual NIU MATH CONTEST
Wednesday, April 20th, 2022, 7-10 pm, DU204
Only currently enrolled NIU undergraduates are eligible!

There will be a Zoom colloquium this Friday delivered by Rita Jimenez Rolland (National Autonomous University of Mexico) at 4PM.

Title: Stability patterns in algebra and topology

Abstract: In this talk we will consider configuration spaces of n points in a manifold and we will survey how the topology of these spaces changes as the parameter n grows. We will describe a framework that allows us to find and predict patterns of algebraic invariants of these and other families of spaces that appear naturally in algebra and topology.

Title: Eremenko’s Conjecture and Wandering Lakes of Wada
Abstract: In 1989, Eremenko investigated the set of points that escape to infinity under iteration of a transcendental entire function, the so-called escaping set. He proved that every component of the closure of the escaping set is unbounded and conjectured that all the components of the escaping set are unbounded. Much of the recent work on the iteration of entire functions is involved in investigating properties of the escaping set, motivated by Eremenko's conjecture. We will begin by introducing many of the basic dynamical properties of iterates of an analytic function, and finally discuss constructing a transcendental entire function with a point connected component of the escaping set, providing a counterexample to Eremenko's conjecture. This is joint work with David Martí-Pete and Lasse Rempe.

The Laplacian and friends: old, new and conjectured spectral bounds

Eigenvalues of the Laplacian have intrigued physicists and mathematicians for hundreds of years: they represent quantities such as frequencies of drums and energy levels of quantum particles, while encoding geometric information such as area, perimeter and curvature integrals. I will provide a tour of classical and recent results for these eigenvalues, with an emphasis on open problems.
