SUMMARY:Raphael Stuhlmeier (Plymouth)
DESCRIPTION:On particle trajectories for Stokes’ edge waves \nAbstract: The matter of particle motion beneath water waves is one of the most natural of questions; it is immediately clear from observations that water particles do not generally travel with the speed of the waveform\, but the exact character of their motion in different types of waves has been the matter of much investigation. We treat the particle motion in Stokes’ linear edge wave\, which propagates along a uniformly sloping beach: a three-dimensional wave with variation in the cross-shore and long-shore directions. Using analogies between the exact\, rotational solution developed by Gerstner and linear water wave theory\, and an appropriate rotation of the coordinate frame\, we show that there is no particle motion in the direction orthogonal to the sloping beach. Some applications to weakly nonlinear edge waves\, as well as modern results by Constantin\, Ehrnström\, and Villari on particle paths will also be discussed. \nThis seminar is suitable for undergraduates as well as interested staff. \n

SUMMARY:Ángel González-Prieto (Universidad Complutense de Madrid)
DESCRIPTION:Duality in Topological Quantum Field Theories\nIn this talk\, we will study Topological Quantum Field Theories (TQFT for short) as powerful tools for understanding and computing topological invariants. We will review some of the categorical machinery needed\, like monoidal categories\, and their physical inspiration as models for path integrals. Focusing on the case of surfaces\, we will characterize 2d TQFT in purely algebraic terms as Frobenius algebras. \nAs these low dimensional cases show\, the monoidality of these constructions imposes very strong duality restrictions on the theory\, which lie in the germ of Baez and Dolan’s cobordism hypothesis. Finally\, we will explain how these difficulties can be overcome by considering lax monoidal TQFT and almost TQFT and how they can be used for explicit computations of topological invariants. \n

SUMMARY:Ángel González-Prieto (Universidad Complutense de Madrid)
DESCRIPTION:Quantization of Hodge structures of representation varieties\nGiven a complex algebraic group $G$ and a compact manifold $M$\, the set of representations $\rho: \pi_1(M) \to G$ has a natural algebraic structure\, the so-called representation variety. In this talk\, we will show how the mixed Hodge structures of these varieties can be encoded in a lax monoidal TQFT via a general quantization procedure by means of Saito’s mixed Hodge modules theory. \nThis strategy recovers the stratification technique developed by Logares\, Muñoz and Newstead and offers a new framework in which mirror symmetry conjectures for $E$-polynomials can be addressed. \nJoint work with M. Logares and V. Muñoz. \n
