Waldhausen's introduction of A-theory of spaces revolutionized the early study of pseudo-isotopy theory. Waldhausen proved that the A-theory of a manifold splits as its suspension spectrum and a factor Wh(M) whose first delooping is the space of stable h-cobordisms, and its second delooping is the space of stable pseudo-isotopies. I will describe a joint project ... Read more about "Toward the equivariant stable parametrized h-cobordism theorem"

Homological stability is a phenomenon that has been studied and established in the context of ordinary group homology for several infinite ascending series of groups. So far the only existing stability result known for bounded cohomology, by Monod, concerned the families of the general and special linear groups over any local field. In this talk ...

Abstract: Traditional model reduction speeds up computations by replacing expensive high-fidelity models with low-cost reduced models. Thus, the goal of traditional model reduction is to construct reduced models that approximate well the high-fidelity models; however, reduced models are increasingly used together with high-fidelity models, which means that the primary purpose of reduced models becomes supporting ...

The goal of this workshop is to discuss the wide set of practical and theoretical applications of the computability of partition functions and address the challenges that arise. Read more about "Applications of Partition Functions"

In this talk we consider two connected problems: First, we study the classical problem of the first passage hitting density of an Ornstein-Uhlenbeck process. We give two complementary (forward and backward) formulations of this problem and provide semi-analytical solutions for both. The corresponding problems are comparable in complexity. By using the method of heat potentials, ... Read more about "Stochastic Processes in Domains with Boundaries and Some of Their Financial Applications"

Abstract: It has been known for several decades that there are close connections between certain classes of singularities in the Minimal Model Program over $\mathbb{C}$ and so-called $F$-singularities which are defined in positive characteristic via Frobenius. There is a more refined conjecture which relates multiplier ideal filtrations and test ideal filtrations. The triviality of certain ...

The Young Topologists Meeting is an annual event for graduate students, recent PhDs and other junior researchers in topology (both pure and applied). Previous editions were organised by the University of Copenhagen, jointly by Stockholm University and the Royal Institute of Technology, and the EPFL. The Young Topologists Meeting 2019 will take place July 22-26 ... Read more about "Young Topologists Meeting"

This workshop brings together dynamicists who use techniques from, and are motivated by, combinatorics, geometry, and number theory. The topics cover a broad swath of dynamics, including ergodic theory, homogeneous dynamics, symbolic dynamics, Teichmuller theory, and billiards, and the aim of the workshop is to highlight the common features across these subjects.
