Sign-changing solutions for a fractional Choquard equation with power nonlinearity

Existence of Ground State Solutions for Choquard Equation with the Upper Critical Exponent

“…For a few decades, variational approaches have been used to study qualitative properties and the existence of the Choquard equation. In recent years, there has been thorough research into the presence of a ground state solution for the Choquard equation, as documented in references [23][24][25][26][27][28][29][30][31]. For a more comprehensive understanding of variational methods, readers are encouraged to consult the following references [32][33][34][35].…”
