Some Classes of Pseudoconvex Fractional Functions via the Charnes-Cooper Transformationunction and a linear one. Furthemore we prove that the ratio between a quadratic fractional function and the cube of an affine one is pseudoconvex if and only if the product between a quadratic fractional function and an affine one is pseudoconvex and we provide a sort of canonical form for this lat
