| contents | In this work, we establish the multiplicity of positive solutions for the following critical fractional Choquard equation with a perturbation on the star-shaped bounded domain $$ \left\{ \begin{array}{lr}
(-Δ)^s u = λu +α|u|^{p-2}u+ \left( \int\limits_Ω \frac{|u(y)|^{2^{*}_{μ,s}}}{|x-y|^ μ}\, dy\right) |u|^{2^{*}_{μ,s}-2}u\; \text{in} \; Ω,\\ u>0\; \text{in}\; Ω,\; \\ u = 0\; \text{in} \; \mathbb{R}^{N}\backslashΩ, \\ \int_Ω|u|^2 dx=d, \end{array} \right. $$ where, $s\in(0,1), N>2s$, $α\in \mathbb{R}$, $d>0$, $2<p<2^*_s:=\frac{2N}{N-2s}$ and $2^{*}_{μ,s}:=\frac{2N-μ}{N-2s}$ represents fractional Hardy-Littlewood-Sobolev critical exponent. Using the minimization technique over an appropriate set and the uniform mountain pass theorem, we prove the existence of first and second solutions, respectively. |
