(Elsevier, 2009)In this paper, we show that the orbits of some simple group actions parametrize cubic rings and quaternion rings.
(2005)We study congruences of the form F(j(z)) | U(p) = G(j(z)) mod p, where U(p) is the p-th Hecke operator, j is the basic modular invariant 1/q+744+196884q+... for SL2(Z), and F,G are polynomials with integer coefficients. ...
