Title: Asymptotic properties of ground states of a semilinear elliptic problem with a vanishing parameter.
Abstract: We consider an elliptic problem with a double-well nonlinearity and a vanishing parameter. The behaviour of solutions depends sensitively on whether a power in the nonlinearity is less, equal or bigger than the critical Sobolev exponent. In the most delicate critical Sobolev regime the asymptotic behaviour of the solutions is given by a particular solution of the critical Emden-Fowler equation, whose choice depends on in a non-trivial way on the space dimension.
Joint work with Cyrill Muratov (NJIT).

Title: Quantum representations and monodromies of fibered links
Abstract: According to a conjecture of Andersen, Masbaum and Ueno, the Witten-Reshetikhin-Turaev quantum representations of mapping class groups send pseudo-Anosov mapping classes to infinite order elements, when the level is big enough. We relate this conjecture to a properties about the growth rate of Turaev-Viro invariants, and derive infinite families of pseudo-Anosov mapping classes that satisfy the conjecture, in all surfaces with n boundary components and genus g>n>=2. These families are obtained as monodromies of fibered links containing some specific sublinks.
