Existence of three positive solutions to nonlinear boundary value problems
Summary: Criteria are established for the existence of three solutions to the boundary value problem \[ Lx=f(t,x),\;w_1x(0)-w_2x'(0)=0=w_3x(1)+w_4x'(1), \] where \(Lx:=-(px')'+qx\). Here, \(p\in C^1[0,1]\), \(p>0\), \(q\in C[0,1]\), \(q\geq 0\).
