Some existence and uniqueness results for logistic Choquard equation

We consider the following doubly nonlocal nonlinear logistic problem driven by the fractional $p$-Laplacian \begin{equation*} \pl u = f(x,u) -\cq ~\text{in}~ \O, ~u=0 ~\text{in}~ \Rn\setminus\O. \end{equation*} Here $ \O \subset \Rn (N\geq2)$ is a bounded domain with $ C^{1,1}$ boundary $\partial \O$, $ s \in (0,1) $, $p \in (1,\infty)$ are such that $ps < N$. Also $p_{s,\a}^\#\leq r<\infty$ , where $p_{s,\a}^\#=(2N-\a)/2N$. Under suitable and general assumptions on the nonlinearity $f$, we study the existence, nonexistence, uniqueness, and regularity of weak solutions. As for applications, we treat cases of subdiffusive type logistic Choquard problem. We also consider in the superdiffusive case the Brezis-Nirenberg type problem with logistic Choquard and show the existence of a nontrivial solution for a suitable choice of $\l$. Finally for a particular choice of $f$ viz. $f(x,t)=\l t^{q-1}$ with $1
