Positive radial solutions for Dirichlet problems via aHarnack-type inequality.Math Meth Appl Sci. 2022;1-14. doi:10.1002/mma.86821099-1476http://hdl.handle.net/10347/29253We deal with the existence and localization of positive radial solutions for Dirichlet problems involving -Laplacian operators in a ball. In particular, -Laplacian and Minkowski-curvature equations are considered. Our approach relies on fixed point index techniques, which work thanks to a Harnack-type inequality in terms of a seminorm. As a consequence of the localization result, it is also derived the existence of several (even infinitely many) positive solutionseng© 2022 The Authors.
