Abstract
Kikuta, Kodama and Nagaoka proved that almost all Fourier coefficients of the Siegel cusp form of degree two and weight 35 are divisible by the prime p=23. We will show that similar congruences hold for the Fourier coefficients of many reflective Borcherds products on O(n, 2). This is joint work with Haowu Wang.
