Exact number of positive solutions for a class of quasilinear boundary value problems with a singular nonlinearity

摘要

Using the time-mapping approach, we study the exact multiplicity of positive solutions of the boundary value problem [Equation Required] where ?p (y) = |y| ~(p-2) y; y ε ?, p > 1, λ > 0 and -1 < -α < q < p - 1.
