Construction of non-constant lower and upper functions for impulsive periodic problems
We present conditions ensuring the existence of piecewise linear lower and upper functions for the nonlinear impulsive periodic boundary value problem $u''=f(t,u,u'),$ $u(t_i+)=\mathrm{J}_i(u(t_i)),$ $u'(t_i+)=\mathrm{M}_i(u'(t_i)),$ $i=1,2,\dots,m,$ $u(0)=u(T),\,\,u'(0...
