 nby Francesco Bastianelli (Università degli Studi di Bari Aldo Moro) as p
 art of UConn Algebra Seminar\n\n\nAbstract\nGiven an irreducible projectiv
 e variety \\(X\\)\, the covering gonality of \\(X\\) is the least gonality
  of an irreducible curve \\(E\\) contained in \\(X\\) and passing through 
 a general point of \\(X\\).\nIn recent years\, this birational invariant h
 as been studied for various algebraic varieties\, as e.g. hypersurfaces of
  the projective space and abelian varieties.\nIn this talk we will report 
 on a joint work with Nicola Picoco\, and we will be concerned with the cov
 ering gonality of the \\(k\\)-fold symmetric product \\(C_k\\) of a smooth
  complex projective curve \\(C\\) of genus \\(g>k\\).\nIn particular\, we 
 will show that for \\(k=2\,3\,4\\)\, the covering gonality of \\(C_k\\) eq
 uals the gonality of the curve \\(C\\).\nMoreover\, we will see that under
  mild assumptions of generality on \\(C\\)\, the only curves \\(E\\) passi
 ng through a general point of \\(C_k\\) and having the same gonality as \\
 (C\\) are copies of \\(C\\) of the form \\(p+C\\)\, where \\(p\\) is a poi
 nt of \\(C_{k-1}\\).\n

 Many results about the geometry of the moduli space of curves $\\mathcal{M

 r\n\n\nAbstract\nThe error-correcting code is a technique for removing the
  noise which occurred in the process of transmitting information and is wi
 dely used in our everyday life\, e.g. CD players or QR codes. By means of 
 the codes based on algebraic curves originally introduced by V.D.Goppa\, T
 sfasman-Vladut-Zink has shown the existence of codes with very good asympt
 otic properties which improved the Gilbert-Varshamov bound.\n\nIn this lec
 ture\, we discuss the parameters of algebraic geometric codes obtained fro
 m higher dimensional varieties. Especially we give estimates for the minim
 um distances of the codes on certain fibered varieties over a curve. By me
 ans of the Seshadri constants\, we also explain some results concerning th
 e codes defined from vector bundles of higher rank.\n

 a Manivel (University of Minnesota) as part of UConn Algebra Seminar\n\n\n
 Abstract\nAround 1915\, Polya and Hilbert independently speculated that se
 lf-adjoint operators could prove the Riemann Hypothesis for zeros of L-fun
 ctions\, and roughly 70 years later\, Colin de Verdière advanced this ide
 a by suggesting a physics-oriented way to make inhomogeneous equations int
 o homogeneous ones. Making this rigorous\, Bombieri and Garrett in the 201
 0's showed that the simplest instance of Colin de Verdière's idea does no
 t succeed because at most 94% of the zeros of zeta can participate in the 
 spectrum of such operators. That is\, the discrete spectrum is small. This
  motivates understanding analogous operators with a large discrete spectru
 m. To do so\, we build on the well-known identification of the universal e
 nveloping algebra of a Lie algebra with the algebra of left invariant diff
 erential operators on the group\, recall an intrinsic characterization of 
 the Laplacian/Casimir on spaces of automorphic forms\, and discuss how we 
 can attempt to understand the spectrum of related automorphic differential
  operators.\n

 robenius pushforward of a line bundle on a projective space decomposes as 
 a direct sum of line bundles\, and similar results are known for toric var
 ieties and quadrics. In this talk we will present a generalization of Hart
 shorne's theorem to higher rank vector bundles on projective spaces and we
  will explain how it can be used to compute cohomology of some vector bund
 les. Surprisingly\, almost all discussed results are valid also in charact

  classes</a>\nby Tyler Genao (Ohio State University) as part of UConn Alge
 bra Seminar\n\n\nAbstract\nIn 1996\, Merel showed that for any elliptic cu
 rve $E$ defined over a number field $F$ of degree $d\\in\\mathbb{Z}^+$\,  
 the size of the torsion group of $E$ over $F$ is bounded by a constant $B:
 =B(d)$ which depends only on $d$. Regarding $B$ as a function of $d$\, it 
 is conjectured that $B$ can be polynomial in $d$. \nIn this talk\, I will 
 discuss recent joint work with Abbey Bourdon which shows that $B$ is polyn
 omial in $d$ for torsion from the family $\\mathcal{I}_{\\mathbb{Q}}$ of e
 lliptic curves which are geometrically isogenous to at least one rational 
 elliptic curve. For torsion from the subfamily $\\mathcal{F}_{\\mathbb{Q}}
 $ of elliptic curves with rational $j$-invariant\, our results strengthen 
 prior work of Clark and Pollack.\n

 e minimal extension of \\(k\\) over which every \\(\\ell\\)-adic Galois re

 s not explained by the endomorphism algebra alone.\n\nWe explain how to co

 tiplication. We exploit CM theory to describe the algebra of Tate classes 
 and make the Galois action on this algebra explicit in terms of periods 
 — suitable integrals of algebraic differential forms. Though periods are
  generally transcendental\, those attached to Tate classes are algebraic\,
  so computing \\(k(eA)\\) reduces to identifying these periods as exact al
 gebraic numbers.\n
