We shall employ some fixed-point theorems for operators on a cone to obtain existence criteria for (at least) three positive solutions of the following continuous and discrete systems of boundary value problems: 2,...,m and (-1) ~-p, A~yi(k) = Fi(k, ~l(k), ~2(k) ..... ~m(k)),

โฆ Synopsis
We consider the following boundary value problems:
n > 2, t e (0,1),
and
(-1)n-PAny=F(k,y, Ay,...,An-ly), n>2, 0<k<m,
where 1 < p < n -1 is fixed. By employing fixed-point theorems for operators on a cone, existence criteria are developed for multiple (at least three) positive solutions of the boundary value problems.
As an application, we also establish the existence of radial solutions of certain partial difference equations. Several examples are included to dwell upon the importance of the results obtained.
