Abstract

We prove generic multiplicity of solutions for a scalar field equation on compact surfaces via Morse inequalities. In particular our result improves significantly the multiplicity estimate which can be deduced from the degree-counting formula in Chen and Lin (doi:10.1002/cpa.10107). Related results are derived for the prescribed Q-curvature equation
