DESCRIPTION:Speaker: Lilybelle Cowland Kellock (UCL)\n\nTitle: A generali
 sation of Tate’s algorithm for hyperelliptic curves\n\nAbstract: Tate's 
 algorithm tells us that\, for an elliptic curve E over a discretely valu
 ed field K with residue characteristic >= 5\, the dual graph of the spec
 ial fibre of the minimal regular model of E over K^{unr} can be read off
  from the valuation of j(E) and \\Delta_E. This is really important for 
 calculating Tamagawa numbers of elliptic curves\, which are involved in 
 the refined Birch and Swinnerton-Dyer conjecture formula. For a hyperell
 iptic curve C/K\, we can ask if we can give a similar algorithm that giv
 es important data related to the curve and its Jacobian from polynomials
  in the coefficients of a Weierstrass equation for C/K. This talk will b
 e split between being an introduction to cluster pictures of hyperellipt
 ic curves\, from which the important data can be gathered\, and a presen
 tation of how the cluster picture can be recovered from polynomials in t
 he coefficients of a Weierstrass equation.\n\nRoom: Frank Adams 1
