 ">Level Lowering via the Deformation theory of Galois Representations</a>\
 nby Anwesh Ray (University of British Columbia) as part of SFU NT-AG semin
 ar\n\n\nAbstract\nElliptic curves defined over the rational numbers arise 
 from \ncertain modular forms. This is the celebrated Modularity theorem of
  Wiles \net al. Prior to this development\, Ribet had proved a level lower
 ing \ntheorem\, thanks to which one is able to optimize the level of the m
 odular \nform in question. Ribet's theorem combined with the modularity th
 eorem of \nWiles together imply Fermat's Last theorem.\n\nIn joint work wi
 th Ravi Ramakrishna\, we develop some new techniques to\nprove level lower
 ing results for more general Galois representations.\n
