Hilbert modular Eisenstein congruences of local origin

Dan Fretwell, Jenny Roberts

Let $F$ be an arbitrary totally real field. Under weak conditions we prove the existence of certain Eisenstein congruences between parallel weight $k \geq 3$ Hilbert eigenforms of…

Symmetric bilinear forms, superalgebras and integer matrix factorization

Dan Fretwell, Jenny Roberts

We construct and investigate certain (unbalanced) superalgebra structures on $End_{K} (V)$ , with $K$ a field of characteristic $0$ and $V$ a finite dimensional $K$ -vector space…

Newform Eisenstein Congruences of Local Origin

Dan Fretwell, Jenny Roberts

We give a general conjecture concerning the existence of Eisenstein congruences between weight $k \geq 3$ newforms of square-free level $N M$ and weight $k$ new Eisenstein series of…
