Abstract Gouvea and Mazur made a precise conjecture about slopes of modular forms. Weaker versions of this conjecture were established by Coleman and Wan. In this Note, we exhibit examples contradicting the full conjecture as it currently stands. To cite this article: K. Buzzard, F. Calegari, C. R. Acad. Sci. Paris, Ser. I 338 (2004). 
Slopes of modular forms and the ghost conjecture (unabridged version)
We formulate a conjecture on slopes of overconvergent p-adic cuspforms of any p-adic weight in the Gamma_0(N)-regular case. This conjecture unifies a conjecture of Buzzard on classical slopes andExpand
Slopes of modular forms and reducible Galois representations: an oversight in the ghost conjecture
The ghost conjecture, formulated by this article’s authors, predicts the list of p-adic valuations of the non-zero ap-eigenvalues (“slopes”) for overconvergent p-adic modular eigenforms in terms ofExpand

Computing overconvergent forms for small primes
In this note, we construct explicit bases for spaces of overconvergent $p$-adic modular forms when $p=2,3$ and study their stability under the Atkin operator. The resulting extension of theExpand
An explicit computation of the Hecke operator and the ghost conjecture
In this paper, we investigate the Hecke operator at p = 5 and show that the upper minors of the matrix have non zero corank and, interestingly, follow the same ghost pattern in the Ghost conjectureExpand
Questions about slopes of modular forms
— We formulate a conjecture which predicts, in many cases, the précise padic valuations of the eigenvalues of the Hecke operator Tp acting on spaces of classical modular forms. The conjecture hasExpand
Upper bounds for constant slope p-adic families of modular forms
We study $p$-adic families of eigenforms for which the $p$-th Hecke eigenvalue $a_p$ has constant $p$-adic valuation ("constant slope families"). We prove two separate upper bounds for the size ofExpand

We describe a new approach to the theory of p-adic families of modular forms, which is based on a comparison of trace formulas. We apply it to give new proofs for the existence of p-adic continuousExpand
Local constancy of dimensions of Hecke eigenspaces of automorphic forms
Abstract We use a method of Buzzard to study p -adic families of Hilbert modular forms and modular forms over imaginary quadratic fields. In the case of Hilbert modular forms, we get local constancyExpand
