Analysis seminar: Theodore Drivas (Stony Brook)
Title: Vibrodynamics of constrained mechanical systemsAbstract: We study the effect of rapid vibration of constraining surfaces of arbitrary codimension on a confined mechanical particle. The slow dynamics experience an effective potential force coming from the geometry of the vibrating surface, which can introduce new equilibria and change stability character of existing ones. A classical example […]
Algebraic Geometry Seminar: Trevor Jones (JHU)
Title: Projectivity of the Moduli Space of Equidimensional BranchvarietiesAbstract: A branchvariety of a projective $k$-scheme $X$ is a geometrically reduced scheme $Y$ equipped with a finite map to $X$. Alexeev and Knutson showed the existence of a proper moduli space of branchvarieties with fixed numerical invariants, but the projectivity of this space remained an open question. In […]
Topology Seminar: Mengwei Hu (Yale University)
Title: On certain Lagrangian subvarieties in minimal resolutions of Kleinian singularitiesAbstract: Kleinian singularities are quotients of C^2 by finite subgroups of SL_2(C). They are in bijection with the ADE Dynkin diagrams via the McKay correspondence. In this talk, I will introduce certain singular Lagrangian subvarieties in the minimal resolutions of Kleinian singularities that are related […]
Math Physics Seminar: Andrew Lawrie (University of Maryland)
Title: Soliton dynamics for classical scalar fields Abstract: I will present some of my recent work with Jacek Jendrej. We study classical scalar fields in dimension 1+1 with a symmetric double-well self-interaction potential. Examples of such equations are the phi-4 model and the sine-Gordon equation. These nonlinear wave equations admit non-trivial static solutions called kinks and […]
