[ 1 ] - On the existence of solution for a $k$-dimensional system of three points nabla fractional finite difference equations

In this paper, we investigate the existence of solution for a k-dimensional system of three points nabla fractional finite difference equations. Also, we present an example to illustrate our result.

[ 2 ] - Some approximate fixed point results for proximinal valued $beta$-contractive multifunctions

In this paper, we prove some approximate fixed point results for proximinal valued $beta$-contractive multifunctions on metric spaces. We show that our results generalize some old fixed point results in the literature.

[ 3 ] - $varepsilon$-Simultaneous approximations of downward sets

In this paper, we prove some results on characterization of $varepsilon$-simultaneous approximations of downward sets in vector lattice Banach spaces. Also, we give some results about simultaneous approximations of normal sets.
