Given a congruence of Hecke eigenvalues between newforms f and g of odd, square free
level, and weight 2 κ - 2 \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} …

Following Ryan and Tornaría, we prove that moduli of congruences of Hecke eigenvalues,
between Saito–Kurokawa lifts and non-lifts (certain Siegel modular forms of genus 2), occur …

We study nearly holomorphic Siegel Eisenstein series of general levels and characters on ℍ
2 n, the Siegel upper half space of degree 2 n. We prove that the Fourier coefficients of these …

Let f be a newform of level 1 and weight (2 κ− n) for positive even integers κ and n. We study
congruence primes for the Ikeda lift of f. In particular, we consider a conjecture of Katsurada …

It has been well established that congruences between automorphic forms have far-
reaching applications in arithmetic. In this paper, we construct congruences for Siegel …

For an imaginary quadratic field K of discriminant− D, let χ= χ K be the associated quadratic
character. We will show that the space of special hermitian Jacobi forms of level N is …

In this paper we provide a sufficient condition for a prime to be a congruence prime for an
automorphic form f on the unitary group U (n, n)(AF) for a large class of totally real fields F …

We prove (under certain assumptions) the irreducibility of the limit σ 2 of a sequence of
irreducible essentially self-dual Galois representations σ k: GQ→ GL 4 (Q¯ p)(as k …
