Graef,Lingju Kong,Qingkai Kong,Min Wang Keywords:Fractional $q$-calculus;Boundary value problems;Positive solutions;Existence;Uniqueness Abstract: The authors study a class of nonlinear higher order boundary value problem with fractional $q$-erivativesand dependence on a positive parameter $\lm$.The existence, uniqueness, and dependence of positive solutions on $\lm$ are discussed.Two sequences are constructed so that they converge uniformly to the unique solution of the problems.Two examples are included in the paper. Numerical computations of the examples confirm their theoretical results. PDF      Download reader
