 e about the Klein quartic\,  an example of many of the phenomena studied i
 n this program. It's a Belyi surface\, it corresponds to a finite index su

 n be explicitly written down as an algebraic curve. In the first of these 
 lectures\, I will discuss the various descriptions of this surface and lin

 en very few explicit methods for them. In this talk\, \nwe will explain ho
 w we might use hypergeometric functions to express modular forms on a Shim

 ation and Modularity at BP\, Pune\, India.\n\n\nAbstract\nIn this talk we 
 will discuss Belyi-Wolfart curves\, namely compact Riemann surfaces X of g
 enus at least 2 such that X -> X/Aut(X) is a Belyi map.  For each g \\geq 
 2 this is yields a finite\, nonempty set of isomorphism classes algebraic 
 curves\, and of course each is defined over Q-bar\, so it is interesting t
 o ask for the fields of moduli of such curves.  \n\nThese curves include a
 s special cases several classical families: the Fermat curves\, the Hurwit
 z curves and the classical modular curves X(N) (for N \\geq 7). The latter
  family motivates us to introduce a family of Belyi-Wolfart curves with Ga
 lois group PSL_2(F_q) or PGL_2(F_q) studied by the speaker and John Voight

 zation and Modularity at BP\, Pune\, India.\n\n\nAbstract\nIn this talk we
  define and study the algebraic curves mentioned above.  As Riemann surfac
 es they are uniformized by principal congruence subgroups of hyperbolic tr
 iangle groups.  As such they provide an interesting challenge to the arith
 metic/non-arithmetic dichotomy for Riemann surfaces: each of these Riemann
  surfaces is naturally associated to a quaternion algebra over a totally r
 eal number field\, but nevertheless all but finitely many of them are non-
 arithmetic.  After recalling what this means\, we attempt to show that  th
 is family of curves is still arithmetically interesting: in particular\, t
 hey all have field of moduli contained in a quadratic extension of an abel
 ian number field.\n
