        "description":"Abstract: I will first discuss the notion of automorphic representations on a unitary group that are $P$-ordinary (at $p$), where $P$ is some parabolic subgroup. I will describe their local structure, as well as the geometry of a $P$-ordinary family $C_\\pi$, using the theory of types. Then, I will introduce a $p$-adic family of Eisenstein series (an Eisenstein measure) that is \u201ccompatible\u201d with $C_\\pi$, using an algebraic version of the doubling method. I will conclude by explaining how this Eisenstein measure corresponds to a $p$-adic $L$-function for $C_\\pi$ viewed as an element of a $P$-ordinary Hecke algebra. These results generalize the ones obtained by Eischen-Harris-Li-Skinner in the ordinary setting and are from the speaker\u2019s thesis.",

        "description":"Planar orthogonal polynomials in the double scaling limit have been much studied for their connection to Coulomb gas system in two dimensions.   Most exact results have been known either for radially symmetric potential or for so-called Hele-Shaw potential, where the limiting density of the Coulomb gas is uniform over its support.   When the potential is not Hele-Shaw type nor radially symmetric, we expect to observe a new type of singular behaviors.   Unfortunately, in such cases, there is no known multiple orthogonality that we can use for asymptotic analysis of the planar polynomials.   \r\n\r\nIn this talk, we will propose a matrix Riemann-Hilbert problem for some polynomial potential that is not radially symmetric and not Hele-Shaw type.   More explicitly we will consider the case when the Laplacian of the potential is |z|^2.  This work is a preliminary report of the work by Abril Arenas and by Seong-Mi Seo.\r\n\r\nEmail eblackst@umich.edu for the zoom link.",
