Ground state solutions and decay estimation of Choquard equation with critical exponent and Dipole potential

<p style='text-indent:20px;'>In this paper, we study a class of Choquard equations with critical exponent and Dipole potential. We prove the existence radial ground state solutions for by using refined Sobolev inequality Morrey norm, show that any nonnegative weak have additional decay properties in terms representation.</p>
