Positive solutions for nonlinear operator equations and several classes of applications

Abstract: In this paper, we study a class of nonlinear operator equations x = Ax + x 0 on ordered Banach spaces, where A is a monotone generalized concave operator. Using the properties of cones and monotone iterative technique, we establish the existence and uniqueness of solutions for such equations. In particular, we do not demand the existence of upper-lower solutions and compactness and continuity conditions. As applications, we study first-order initial value problems and two-point boundary value problems with the… Show more

“…We now present a fixed point theorem of generalized concave operators which will be used in the latter proof. See [30] , and let be a normal cone. Assume that ( 1 ) : → is increasing and ℎ ∈ ℎ ; ( 2 ) for any ∈ and ∈ (0, 1), there exists ( ) ∈ ( , 1) with respect to such that ( ) ≥ ( ) .…”

“…These days the fractional q-difference equation have given fire to increasing scholars' imaginations. Some works considered the existence of positive solutions for nonlinear q-fractional boundary value problem [13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32]. For example, Ferreira [13] where γ , β ≤ 0, and c D α q is the fractional q-derivative of Caputo type.…”
