Abstract:
By using the fixed point theorem in cones, in this paper, existence criteria
for single and multiple positive solutions to a class of nonlinear
first-order periodic boundary value problems of impulsive dynamic equations
on time scales are obtained. An example is given to illustrate the main
results in this article.
