Abstract

This paper is concerned with the existence of at least one   positive solution for a boundary value problem (BVP), with  $p$-Laplacian, of the form
    \begin{equation*}
        \begin{split}
            (\Phi_p(x^{'}))^{'} + g(t)f(t,x)  &= 0, \quad t     \in (0,1),\\
            x(0)-ax^{'}(0) = \alpha[x], & \quad
            x(1)+bx^{'}(1) = \beta[x],
        \end{split}
    \end{equation*}
where $\Phi_{p}(x) = |x|^{p-2}x$ is a one dimensional $p$-Laplacian operator with $p>1, a,b$ are real constants and $\alpha,\beta$ are  the Riemann-Stieltjes integrals
    \begin{equation*}
        \begin{split}
            \alpha[x] = \int \limits_{0}^{1} x(t)dA(t), \quad  \beta[x] = \int \limits_{0}^{1} x(t)dB(t),
        \end{split}
    \end{equation*}
with $A$ and $B$ are functions of bounded variation. A Homotopy version of  Krasnosel'skii fixed point theorem is used to prove our results.
