DESCRIPTION:Speaker: Jaitra Chattopadhyay\nhosted by Timothy Browning\nAbst
 ract: In 1979\, H. W. Lenstra defined the notion of an Euclidean ideal cla
 ss andproved that if a number field K has a non-principal Euclidean ideal 
 class then the ideal class group ClK of K is cyclic. Except for the imagin
 ary quadratic fields\, he was able to prove the converse\, under the assum
 ption of GRH. Later\, H. Graves constructed an explicit biquadratic field 
 having an Euclidean ideal class and after a few years C.Hsu provided a fam
 ily of such fields. In this talk\, we shall give a new class of biquadrati
 c fields other than the ones given by Graves and Hsu. This is a joint work
  with Dr. M. Subramani.
