The automorphism group of the modular curve with square-free level
Francesc Bars, Josep González
We determine the automorphism group of the modular curve , obtained as the quotient of the modular curve by the group of its Atkin-Lehner involutions, for all sq…
Hyperelliptic parametrizations of -curves
Francesc Bars, Josep González, Xavier Xarles
For a square-free integer , we present a procedure to compute -curves parametrized by rational points of the modular curve when this is hyperelliptic.
Lie algebraic solution of the Kratzer oscillator in diatomic molecules
Boris Maulén, José Mauricio González
The study of diatomic molecules plays a central role in the understanding of the chemical bond. For their simplicity, they serve as a model for the study of more complex molecular…
Constraints on the automorphism group of a curve
Josep González
For a curve of genus defined over a finite field, we present a criterion which allows us to state the non existence of automorphisms of order a power of a rational prime.…
Automorphism group of split Cartan modular curves
Josep González
We determine the automorphism group of the split Cartan modular curves for all primes .
The automorphism group of the non-split Cartan modular curve of level 11
Valerio Dose, Julio Fernández, Josep González +1
We derive equations for the modular curve associated to a non-split Cartan subgroup of . This allows us to compute the automorphism g…
Frobenius distribution for quotients of Fermat curves of prime exponent
Francesc Fité, Josep González, Joan-Carles Lario
Let C denote the Fermat curve over Q of prime exponent l. The Jacobian Jac(C) of C splits over Q as the product of Jacobians Jac(C_k), 0< k < l-1, where C_k are curves obtained as…
