Title: Three positive solutions for p-Laplacian functional dynamic
       equations on time scales

Author: Da-Bin Wang (Lanzhou Univ., Gansu, China)

Abstract:
 In this paper, we establish the existence of three positive solutions
 to the following p-Laplacian functional dynamic equation on time scales,
 $$\displaylines{
 [ \Phi _p(u^{\Delta }(t))] ^{\nabla}+a(t)f(u(t),u(\mu (t)))=0,\quad
 t\in (0,T)_{\mathbf{T}}, \cr
 u_0(t)=\varphi (t),\quad t\in [-r,0] _{\mathbf{T}},\\
 u(0)-B_0(u^{\Delta }(\eta ))=0,\quad u^{\Delta }(T)=0,.
 }$$
 using the fixed-point theorem due to Avery and Peterson [8].
 An example is given to illustrate the main result.
