Multiple positive solutions of two-point right focal boundary value problems

Three Solutions of Constant Sign for a System of Discrete Equations

“…Note that the P i considered in (4.4) as well as the methodology used are both more general. In [21] it is given that…”

Positive Solutions for Two-Point Semipositone Right Focal Eigenvalue Problem

“…In recent years, many papers have discussed the existence of positive solutions of right focal boundary value problems, see [1][2][3][4][5][6][7]. In 2003, Ma [5] established existence results of positive solutions for the fourth-order semipositone boundary value problems u (4) Motivated by Agarwal and Wong [8] and Ma [5], the purpose of this article is to generalize and complement Ma's work to nth-order right focal eigenvalue problems:…”

“…For other related works with focal boundary value problem, we refer to recent contributions of Agarwal [1], Agarwal et al [2], Boey and Wong [3], He and Ge [4], and Wong and Agarwal [6,7].…”

Right focal boundary value problems for difference equations

“…For well over a decade, substantial results have been obtained for positive solutions and multiple positive solutions for boundary value problems for finite difference equations; see, for example [2,5,10,11,13,15,16,[20][21][22][23][25][26][27][28].…”
