Kelevedjiev (Technical Univ. of Sliven, Bulgaria) Stepan A. Tersian (Univ. of Ruse, Bulgaria) Abstract: We study the solvability of the boundary value problem $$ (\phi_p(x'))'=f(t,x,x'),\quad x(0)=A,\;x'(1)=B, $$ where $\phi_p(s)=s|s|^{p-2}$, using the barrier strip type arguments. We establish the existence of $C^2[0,1]$-solutions, restricting our considerations to $p\in(1,2]$. The existence of positive monotone solutions is also considered. Submitted June 27, 2012.
