Let p = ( P ) be any prime of F q [ t ] , let m be any ideal of F q [ t ] not divisible by p and consider the space of Drinfeld cusp forms of level m p , i.e. for the modular group Γ 0 ( m p ) . Using degeneracy maps, traces and Fricke involutions w

We use a linear algebra interpretation of the action of Hecke operators on Drinfeld cusp forms to prove that when the dimension of the $\mathbb {C}_\infty $ -vector space $S_{k,m}(\mathrm {{GL}}_2(\mathbb {F}_q[t]))$ is one, the Hecke operator $\math

The present paper deals with Atkin–Lehner theory for Drinfeld modular forms. We provide an equivalent definition of $$\mathfrak {p}$$ -newforms (which makes computations easier) and commutativity results between Hecke operators and Atkin–Lehner i

We study the Atkin U t U_t operator for Drinfeld cusp forms. In particular, we define newforms and oldforms of level Γ 0 ( t ) \Gamma _0(t) and we study basic properties of their slopes. Moreover, we find an explicit formula for the matrix associate

Let A be an abelian variety defined over a global function field F of positive characteristic p and let K / F be a p-adic Lie extension with Galois group G. We provide a formula for the (truncated) Euler characteristic χ ( G , S e l A ( K ) p ) of t

We define oldforms and newforms for Drinfeld cusp forms of level $t$ and conjecture that their direct sum is the whole space of cusp forms. Moreover we describe explicitly the matrix $U$ associated to the action of the Atkin operator $\mathbf{U}_t$ o

Let F be a global function field of characteristic p > 0 and A/F an abelian variety. Let K/F be an l-adic Lie extension (l ≠ p) unramified outside a finite set of primes S and such that Gal(K/F) has no elements of order l. We shall prove that, unde
