Let p ≡ - q ≡ 5 ( mod 8 ) be two prime integers. In this paper, we investigate the unit groups of the fields L 1 = Q ( 2 , p , q , - 1 ) and L 1 + = Q ( 2 , p , q ) . Furthermore , we give the second 2-class groups of ...

We study Diophantine equations of type f ( x ) = g ( y ) , where both f and g have at least two distinct critical points (roots of the derivative) and equal critical values at at most two distinct critical points. Various classical familie...
