Some Solvability Theorems for Nonlinear Equations

چکیده
Let E be a locally convex space and f : E → E a mapping. We say that the equation f(x) = 0 is almost solvable on A ⊂ E if 0 ∈ f(A). In this paper some results about the solvability and almost solvability are given. Our results are based on some classical fixed point theorems and on some geometrical conditions.

A Generalization of the Meir-Keeler Condensing Operators and its Application to Solvability of a System of Nonlinear Functional Integral Equations of Volterra Type
In this paper, we generalize the Meir-Keeler condensing operators via a concept of the class of operators $ O (f;.)$, that was given by Altun and Turkoglu [4], and apply this extension to obtain some tripled fixed point theorems. As an application of this extension, we analyze the existence of solution for a system of nonlinear functional integral equations of Volterra type. Finally, we p...
متن کاملSome Solvability Theorems for Nonlinear Equations with Applications to Projected Dynamical Systems
The study of solvability of nonlinear equations defined in topological vector spaces is a fundamental problem considered in Nonlinear Analysis. This problem is so important because it is related to the study of solvability of differential or integral equations. The literature related to this subject is huge. See [1]–[4], [7], [10], [11], [17], [23]–[25] among the other papers and books publishe...

متن کاملA Fixed Point Theorem for a Class of Differentiable Stable Operators in Banach Spaces
We study Fréchet differentiable stable operators in real Banach spaces. We present the theory of linear and nonlinear stable operators in a systematic way and prove solvability theorems for operator equations with differentiable expanding operators. In addition, some relations to the theory of monotone operators in Hilbert spaces are discussed. Using the obtained solvability results, we formula...
