[EN] Assessing and monitoring river areas is necessary to support river management
and restoration processes. As rivers change over short periods of time
assessment methods need to be quick, reliable and cost/time-effective. ...

[EN] This article introduces free group representations of planar vortexes in a CW space that are a natural outcome of results for amenable groups and fixed points found by M.M. Day during the 1960s and a fundamental result ...
[EN] In this paper, we introduce the notions of generalized α-F-contraction and modified generalized α-F-contraction. Then, we present sufficient conditions for existence and uniqueness of fixed points for the above kind ...
A sufficient condition for the existence and uniqueness of fixed point for a new variant of cyclic contractive mapping, named as weakly cyclic contractive mappings, involving a generalized altering distance function in ...
Rus (Approx. Convexity 3:171–178, 2005) introduced the concept of cyclic contraction
mapping. P˘acurar and Rus (Nonlinear Anal. 72:1181–1187, 2010) proved some fixed
point results for cyclic φ-contraction mappings on a ...

[EN] The purpose of this paper is to introduce the class of enriched interpolative Kannan type operators on Banach space that contains theclasses of enriched Kannan operators, interpolative Kannan type contraction operators ...
[EN] In this paper we study the existence of the fixed points for Hardy-Rogers type mappings with respect to a wt-distance in partially ordered metric spaces. Our results provide a more general statement, since we replace ...
[EN] In this manuscript, by using the weight-function technique, a new class of iterative methods for solving nonlinear problems is constructed, which includes many known schemes that can be obtained by choosing different ...
Boxer, Laurence(Universitat Politècnica de València, 2020-04-03)
[EN] We continue the work of [10], studying properties of digital images determined by fixed point invariants. We introduce pointed versions of invariants that were introduced in [10]. We introduce freezing sets and cold ...

[EN] New fixed point and coupled fixed point theorems in partially ordered ν-generalized metric spaces are presented. Since the product of two ν-generalized metric spaces is not in general a ν-generalized metric space, a ...
We prove a fixed point theorem for cyclic orbital generalized contractions on complete metric spaces from which
we deduce, among other results, generalized cyclic versions of the celebrated Boyd and Wong fixed point ...
