Indefinite integrals of special functions from integrating factors

Integral transforms and special functions, 2020
Some general integrals are presented which were obtained from two integrating factors and for the first two and last two terms, respectively, of the second-order linear ordinary differential equation obeyed by many special functions.

Families of analytic solutions for (2+1) model in unbounded domain via optimal Lie vectors with integrating factors

Modern physics letters B, 2019
Through the commutator table and the adjoint table between the infinitesimals, we apply two stages of Lie symmetry reduction to reduce the (2[Formula: see text]+[Formula: see text]1)-dimensional Boiti–Leon–Manna–Pempinelli (BLMP) equation to ordinary ...
