Ramanujan-style congruences for prime level

نویسندگان

چکیده

We establish Ramanujan-style congruences modulo certain primes $$\ell $$ between an Eisenstein series of weight k, prime level p and a cuspidal newform in the $$\varepsilon -eigenspace Atkin–Lehner operator inside space cusp forms k for $$\Gamma _0(p)$$ . Under mild assumption, this refines result Gaba–Popa. use these recent work Ciolan, Languasco third author on Euler–Kronecker constants, to quantify non-divisibility Fourier coefficients involved by .$$ The degree number field generated we investigate using results factors shifted numbers.

Ramanujan Congruences for Siegel Modular Forms

We determine conditions for the existence and non-existence of Ramanujan-type congruences for Jacobi forms. We extend these results to Siegel modular forms of degree 2 and as an application, we establish Ramanujan-type congruences for explicit examples of Siegel modular forms.

Ramanujan Type Congruences for a Partition Function

We investigate the arithmetic properties of a certain function b(n) given by ∞ ∑ n=0 b(n)qn = (q; q)−2 ∞ (q 2; q2)−2 ∞ . One of our main results is b(9n + 7) ≡ 0 (mod 9).

An Algorithmic Approach to Ramanujan Congruences

δ|M ∏∞ n=1(1− q )δ = ∑∞ n=0 a(n)q n and three positive integers m, t, p, and which returns true if a(mn + t) ≡ 0 (mod p), n ≥ 0, or false otherwise. A similar algorithm for generating functions of the form ∏∞ n=1(1− q )1 (i.e. the case M = 1) has already been given in [3]. Our original plan was to implement that algorithm in order to prove some congruences from [1]. The algorithm we present her...

Congruences modulo Prime Powers

Let p be any prime, and let α and n be nonnegative integers. Let r ∈ Z and f (x) ∈ Z[x]. We establish the congruence p deg f k≡r (mod p α) n k (−1) k f k − r p α ≡ 0 mod p ∞ i=α ⌊n/p i ⌋ (motivated by a conjecture arising from algebraic topology), and obtain the following vast generalization of Lucas' theorem: If α > 1 and l, s, t are nonnegative integers with s, t < p, then 1 ⌊n/p α−1 ⌋! k≡r (...

Dancing samba with Ramanujan partition congruences

The article presents an algorithm to compute a C[t]-module basis G for a given subalgebra A over a polynomial ring R = C[x] with a Euclidean domain C as the domain of coefficients and t a given element of A. The reduction modulo G allows a subalgebra membership test. The algorithm also works for more general rings R, in particular for a ring R ⊂ C((q)) with the property that f ∈ R is zero if an...
