Abstract:

The authors employ the method of upper and lower solutions coupled with  the monotone iterative technique to obtain results of existence and
 uniqueness for anti periodic  and nonlinear boundary problems of  differential equations with piecewise constant arguments x′(t)=f(t,x(t),x([t-k])), x(0)+h(x(T))=0\$, where \$h(θ)∈C^1(R),h′(θ)>0.

Key words: Anti periodic boundary conditions and nonlinear boundary conditions, Monotone iterative technique, Lower and upper related solutions, Differential equations with piecewise constant arguments, minimal and maximal solutions
