Since x 0 ∈ (0, x ] , y 0 ∈ (0, y ] are arbitrary, substitute x 0 , y 0 with x, y and the proof is complete. Corollary 2.4 : Assume that f(x, y), g(x, y), h(x, y) Î C(R + × R + , R + ), and a, j , ψ , ω , a , b , J, Y are defined as in Theorem 2.3. If u Î C(R + × R + , R + ) satisfies the[r]

In this paper, we study the existence and uniqueness of fuzzy solutions for general hyperbolic partial differential equations with local conditions making use of the Banach fixed point theorem. Some examples are presented to illustrate our results.
Chapter I is focused on the Cauchy–Kowalewski theorem. We discuss the notion of characteristic surfaces and use it to classify partial differential equa- tions. The discussion grows from equations of second-order in two variables to equations of second[r]

Although, according to Nash & Rhodes (1998), the computation of web crippling strength obtained using empirical methods is relatively rapid and safe within their range of application, this does not imply that empirical methods are without drawbacks[r]
