In analysing nonlinear phenomena many mathematical models give rise to problems for
which only nonnegative solutions make sense. In the last few years this discipline has grown …

In the first part of the paper, we establish the existence of multiple positive solutions to the
nonlinear second-order three-point boundary value problem on time scales, u▵▿(t)+ f (t, u …

We will find conditions on f that lead to the existence of at least three positive solutions to the
three-point boundary value problem− x‴(t)+ f (x (t))= 0, with x (0)= x′(t2)= x ″(1)= 0, on [0 …

We establish the existence of at least three positive solutions to the second-order three-point
boundary value problem, u ″+ f (t, u)= 0, u (0)= 0, αu (η)= u (1), where η: 0lt; η< 1, 0< α< 1/η …

The fixed point theorem of cone expansion and compression of norm type is generalized by
replacing the norms with two functionals satisfying certain conditions to produce a fixed point …

We are concerned with the discrete focal boundary value problem Δ3x (t− k)= f (x (t)), x (a)=
Δx (t2)= Δ2x (b+ 1= 0. Under various assumptions on f and the integers a, t2, and b we prove …
