Streszczenie
We study the boundedness in $L^p(\mathbb S^n)$ of the projections onto spaces of functions with spectrum contained in horizontal strips. We obtain some results concerning convergence along nonisotropic regions of harmonic extensions of functions in $L^p(\mathbb S^n)$ with spectrum included in these horizontal strips.
