Perhaps the most important deformations in solid mechanics are those that represent the bending, twisting and extension of beams. The most important flows in fluid mechanics are viscometric flows. In both cases these are the motions that, when...

In this talk I will describe some recent results concerning the connection between the bubblesort sorting algorithm and certain integer sequences used to analyze various juggling patterns. The analysis leads to new results on the joint distribution...

Biological aggregations such as insect swarms, bird flocks, and fish schools are arguably some of the most common and least understood patterns in nature. In this talk, I will discuss recent work on swarming models, focusing on the connection between...

If H is a variation of Hodge structure over a variety S, then there is a family of complex tori J(H) over S associated to H. Admissible normal functions are certain sections of J(H) over S. Roughly speaking, they are the ones that have the...

This talk demonstrates a new metric for measuring phonetic similarity between speech sounds, based on several types of phonetic data collected for a set of 130 consonants and vowels. Phonetic similarity is frequently invoked for explaining a wide...

Equivariant Lefschetz invariants have already appeared in algebraic topology. Here I will show how to approach them using the so-called equivariant KK-theory of Kasparov — the main tool of the new field of noncommutative geometry. I will sketch the...

We study and determine a homotopy type of the moduli space of all generalized Morse functions on d-manifolds for given d. This moduli space is closely connected to the moduli space of all Morse functions studied by Madsen and Weiss and classifying...

After an introduction on Tikhonov regularization for linear inverse problems, we will encounter an example from inverse electromyography, where the classical Tikhonov method runs into numerical trouble. We will then look at an alternative approach...
