Fixed points for E-asymptotic contractions and Boyd-Wong type E-contractions in uniform spaces
In this paper we discuss on the fixed points of asymptotic contractions and Boyd-Wong type contractions in uniform spaces equipped with an E-distance. A new version ofKirk's fixed point theorem is given for asymptotic contractions and Boyd-Wong type contractions is investigated in uniform spaces.
متن کاملTheorems for Boyd-Wong-Type Contractions in Ordered Metric Spaces
and Applied Analysis 3 The purpose of this paper is to generalize the above results using an ICS mapping T : X → X and involving some generalized weak contractions of Boyd-Wong-type 31 . Also, some examples are presented to show that our results are effective. 2. Main Result First, denote by Φ the set of functions φ : 0, ∞ → 0, ∞ satisfying a φ t < t for all t > 0, b φ is upper semicontinuous f...

متن کاملKwong-wong-type Integral Equation on Time Scales
Consider the second-order nonlinear dynamic equation [r(t)x(ρ(t))] + p(t)f(x(t)) = 0, where p(t) is the backward jump operator. We obtain a Kwong-Wong-type integral equation, that is: If x(t) is a nonoscillatory solution of the above equation on [T0,∞), then the integral equation rσ(t)x∆(t) f(xσ(t)) = P(t) + Z ∞ σ(t) rσ(s)[ R 1 0 f (xh(s))dh][x ∆(s)]2 f(x(s))f(xσ(s)) ∆s is satisfied for t ≥ T0,...
متن کاملWong-Zakai type convergence in infinite dimensions
The paper deals with convergence of solutions of a class of stochastic differential equations driven by infinite-dimensional semimartingales. The infinite-dimensional semimartingales considered in the paper are Hilbert-space valued. The theorems presented generalize the convergence result obtained by Wong and Zakai for stochastic differential equations driven by linear interpolations of a finit...
