## Optimality results for a specific fractional problem

 1 LAMA, FSDM, Sidi Mohamed Ben Abdellah University, Fez, Morocco

Received  July 2019 Revised  July 2020 Published  November 2020

In this paper, one minimizes a fractional function over a compact set. Using an exact separation theorem, one gives necessary optimality conditions for strict optimal solutions in terms of Fréchet subdifferentials. All data are assumed locally Lipschitz.
