We establish weighted-Fourier extension estimates for-invariant functions defined on the unit sphere, allowing for exponentspbelow the Stein–Tomas critical exponent. Moreover, in the more general setting of an arbitrary closed subgroupandG-invariant functions, we study the implications of weighted Fourier extension estimates with regard to boundedness and nonvanishing properties of the corresponding weighted Helmholtz resolvent operator. Finally, we use these properties to derive new existence results forG-invariant solutions to the nonlinear Helmholtz equation $$\begin{aligned} -\Delta u - u = Q(x)|u|^{p-2}u, \quad u \in W^{2,p}({\mathbb {R}}^{N}), \end{aligned}$$whereQis a nonnegative bounded andG-invariant weight function.
