Analysis Seminar – Kabe Moen
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Best constants for maximal operators Abstract: In this talk I will survey some known results concerning best constants for the Hardy-Littlewood maximal operator and it’s variants. We will go over the sharp one dimensional theory for the uncentered maximal function. We will also talk about best constants for the dyadic maximal function and some
Algebra Topology Seminar – Tucker Ervin (UA)
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Mutations of reflections and existence of pseudo-acyclic orderings for type An Abstract: In a recent paper by K.-H. Lee, K. Lee and M. Mills, a mutation of reflections in the universal Coxeter group is defined in association with a mutation of a quiver. A matrix representation of these reflections is determined by a linear ordering

Applied Math Seminar – Qiliang Wu (Ohio University)
ZoomTitle: Pearling and Localized Undulation of Bilayers in Amphiphilic Morphology Abstract: Amphiphiles, such as lipids and functionalized polymers, plays a central role in the self-assembly of solvent accessible, intricately structured nano-scaled network structures, which are vital in cell functionality and offer wide applications to drug delivery, detergent production, emulsion stabilization and energy conversion devices. We
Colloquium – David Wright, Washington University St. Louis
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: A Survey of the Illustrious Jacobian Conjecture Abstract: The celebrated Jacobian Conjecture asserts: Let F be a polynomial map from C^n to C^n. If the jacobian determinant of F is everywhere non-vanishing, then F is a polynomial automorphism. This conjecture, now 82 years old and still unsolved for n>1, can be viewed as a
Algebra/Topology Seminar – Fraser Binns (Boston College)
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Some Link Detection ResultsAbstract: A central question in low dimensional topology is; how can we distinguish links? In this talk I will discuss various classical invariants which can help us do so, as well as the stronger invariant Knot Floer homology and, time permitting, annular Khovanov homology. Indeed, we will see that these latter

230 Gordon Palmer Hall 505 Hackberry Lane, AL, United StatesSymplectic topology of Brieskorn singularities – Cagri Karakurt (Bogazici University)
ZoomAbstract: Cagri will talk about some symplectic/contact topological aspects of Brieskorn singularities $x^p+y^q+z^r=0$. He’ll tell how to draw the surgery diagrams of their canonical contact structures and prove that the Milnor fiber $M(p,q,r)$ symplectically embeds into $M(p’,q’,r’)$ whenever $p\leq p’$, $q\leq q’$, and $r\leq r’$ by explicitly constructing a Stein cobordism between corresponding canonical contact
