ZoomTitle: Free Boundary Problem: Challenges and Applications Abstract: There exists a wide range of modern and important physical and Biological phenomena that are described as free boundary problems. The difficulty in solving them stems from the fact that the solution depends on a boundary that evolves in time, at which boundary conditions must be imposed

ZoomTitle: Abstract Infinite Group Theory in Linear Groups. Abstract: It is a classical result that the commutator subgroup of a group $G$ is finite whenever such is the factor group $G/Z(G)$. In general, this result cannot be reverted: there are (soluble) groups with a finite commutator subgroup but an infinite factor over the centre. However,
Analysis Seminar – Olli Saari (University of Bonn)
ZoomTitle: On the weak differentiability of the fractional maximal function Abstract: The fractional maximal functions are comparable in Lp size to the Riesz potentials of same order. Its smoothing properties are however more subtle. In this talk, I will discuss Sobolev regularity of fractional maximal functions on the Euclidean n-space as well as on bounded
Applied Math Seminar – Andrea Giorgini (Indiana University)
ZoomTITLE: Diffuse interface methods for incompressible two-phase flows ABSTRACT: The diffuse interface (or phase field) theory has emerged in the last decades as a versatile approach to describe the interface dynamics in many problems arising from fluid and solid mechanics, image processing, material sciences and biology. Among many, recent applications are Li-ion batteries and tumor
Colloquium – Ralf Schiffler (University of Connecticut)
ZoomTitle: An Introduction to Cluster Algebras Abstract: Cluster algebras are commutative algebras with a special combinatorial structure. They were introduced in 2002 by Sergey Fomin and Andrei Zelevinsky in the context of canonical bases in Lie theory and have quickly developed deep connections to other areas of mathematics and physics, including combinatorics, representation theory, hyperbolic geometry, elementary

ZoomTitle: Necessary and sufficient conditions in weighted theory Abstract: Starting with the L^p boundedness of the Hilbert transform by Riesz in 1928 we go through the development of weighted theory. First Muckenhoupt and the necessary and sufficient A_p condition for one weight inequalities, then Sawyer with the testing conditions on two weight inequalities leading up
