We will disucss some recent advances in the convergence of Anderson acceleration, an extrapolation technique that can be applied to general fixed-point iterations. The theory will be illustrated on some examples of systems arising from finite element...

The (α,β)-superprocess is a spatial branching model associated to an α-stable spatial motion and a (1+β)-stable branching mechanism. Technically, it is a measure-valued Markov process, but this talk concerns the absolutely continuous parameter regime...

The growth regulator auxin plays a central role in development across plants. Auxin spatial patterning is critical in the phyllotactic arrangement of leaves along a stem, the shapes of the leaves themselves, and venation within leaves. These patterns...

The classifying space for commutativity, denoted by B_\text{com} G, of a Lie group G is assembled from commuting tuples in G as a subspace of the usual classifying space BG. The resulting space classifies principal G-bundles whose transition...

A pair of skew shapes are said to be (skew) equivalent if they admit the same number of semistandard tableaux of any weight; i.e. if their associated skew Schur functions are equal. A complete characterization is known for ribbon shapes (those with...

We describe a theorem due to Jianya Liu and Yangbo Ye (Pure and Applied Mathematics Quarterly, Volume 3, Number 2, 481-497, 2007) concerning the prime number theorem for automorphic L-functions. We state the theorem and review the strategy of the...

The PPSZ algorithm, due to Paturi, Pudlak, Saks and Zane, is currently the fastest known algorithm for the k-SAT problem, for every k>3. For 3-SAT, a tiny improvement over PPSZ was obtained by Hertli. We introduce a biased version of the PPSZ...

Peritrichously flagellated bacteria such as E. coli swim in a fluid environment by rotating motors embedded in the cell membrane and consequently rotating multiple helical flagella. We present a mathematical model of a microswimmer that can freely...

In its most well-known form, the Loewner equation gives a correspondence between curves in the upper half-plane and continuous real functions (called the “driving function” for the equation). We consider the generalized Loewner equation, where the...
