Positive Ground State Solutions for Fractional (p,q)-Laplacian Choquard Equation with Singularity and Upper Critical Exponent

Key Points

• The aim is to establish the existence of positive ground state solutions for a specific fractional Choquard equation.
• Utilized Nehari manifold technique to establish solutions.
• Applied Ekeland’s variational principle for existence proof.
• Demonstrated the existence of positive ground state solutions.
• Showed that these solutions are valid despite singularity and achieving upper critical exponent.
