In this note, we study the existence and uniqueness of a positive solution to
a doubly singular fractional problem with nonregular data. Besides, for some
cases, we will show the existence and uniqueness of another notion of a
solution, so-called entropy solution. Also, with suitable assumptions on data,
we will discuss the uniqueness. Finally, we will have some relaxation on the
assumption to prove the existence results.Comment: We are grateful for any feedback or comments. arXiv admin note: text
