in the region t>0. Here x =(Xl, x2 . . . . , xn), u =u(t, x), the f j , j = 1, 2, . . . , n, are continuously differentiable functions of a single real variable, and u0 (x) is in the class F; i.e., Uo(X) is a bounded function having locally bounded variation in the sense of TOt~LLI-CESARI. Moreover for each fixed t, u(t, x) is in the same class F. A function f is said to have bounded variation in the sense of TONeLLI-CEsld~I over a compact set (2 if there exists a set Z of measure zero in Q such that the functions

Existence of positive solution to a class of boundary value problems of fractional differential equations
This paper is devoted to the study of establishing sufficient conditions for existence and uniqueness of positive solution to a class of non-linear problems of fractional differential equations. The boundary conditions involved Riemann-Liouville fractional order derivative and integral. Further, the non-linear function $f$ contain fractional order derivative which produce extra complexity. Than...

متن کاملExistence and uniqueness of the solution for a general system of operator equations in $b-$metric spaces endowed with a graph
The purpose of this paper is to present some coupled fixed point results on a metric space endowed with two $b$-metrics. We shall apply a fixed point theorem for an appropriate operator on the Cartesian product of the given spaces endowed with directed graphs. Data dependence, well-posedness and Ulam-Hyers stability are also studied. The results obtained here will be applied to prove the existe...
