$C^{\infty}$ -structures in the integration of involutive distributions

A. J. Pan-Collantes, C. Muriel, A. Ruiz +1

For a system of ordinary differential equations (ODEs) or, more generally, an involutive distribution of vector fields, the problem of its integration is considered. Among the many…

$λ -$ Symmetries and integrability by quadratures

C. Muriel, J. L. Romero, A. Ruiz

It is investigated how two (standard or generalized) $λ -$ symmetries of a given second-order ordinary differential equation can be used to solve the equation by quadratures. The met…

Solvable Structures Associated to the Nonsolvable Symmetry Algebra $sl (2, R)$

Adrián Ruiz, Concepción Muriel

Third-order ordinary differential equations with Lie symmetry algebras isomorphic to the nonsolvable algebra $sl (2, R)$ admit solvable structures. These solvable…
