Abstract:
We will study the existence of constant sign solutions for the second-order
m-point boundary-value problem
where
,
and
for
, with
,
we obtain that
there exist at least a positive and a negative
solution for the above problem. Our approach is based on
unilateral global bifurcation theorem.
