Generalization of Rakotch's fixed Point TheoremGeneralization of Rakotch's fixed Point Theorem
(Universidad de Costa Rica, Centro de Investigación en Matemática Pura y Aplicada (CIMPA), 2002)
A Lefschetz fixed point theorem for multivalued maps of finite spaces
(Springer, 2019-05-16)
We prove a version of the Lefschetz fixed point theorem for multivaluedmaps F : X ⊸ X in which X is a finite T0 space
Stefan problems for the diffusion-convection equation with temperature-dependent thermal coefficients
(Pergamon-Elsevier Science Ltd, 2021-09)
Different one-phase Stefan problems for a semi-infinite slab are considered, involving a moving phase change material as well as temperature dependent thermal coefficients. Existence of at least one similarity solution is ...
Some fixed point theorems for Kannan mapping in the modular spaces
(Universidade Federal de Santa Maria, 2015)
Surveying the three-dimensional fixed points of T duality
(American Physical Society, 2007-12)
We explore the family of fixed points of T-duality transformations in three dimensions. For the simplest nontrivial self-duality conditions it is possible to show that, in addition to the spacelike isometry in which the ...
On the global dynamic behaviour for a generalized haematopoiesis model with almost periodic coefficients and oscillating circulation loss rate
(John Wiley & Sons Ltd, 2018-07)
A generalized non-linear nonautonomous model for the haematopoiesis (cell production) with several delays and an oscillating circulation loss rate is studied. We prove a fixed point theorem in abstract cones, from which ...
A projection-valued measure for a countable iterated function system
(Birkhauser Verlag Ag, 2021-01-09)
Davison in 2015 used the famous Banach Fixed Point Theorem to prove that a certain class of iterated function systems generated counterparts of the Hutchinson measure in the space of projection-valued measures. In this ...
Integral formulation for a Stefan problem with spherical symmetry
(Birkhauser Verlag Ag, 2021-06)
A one-dimensional Stefan problem with spherical symmetry corresponding to the evaporation process of a droplet is considered. An equivalent integral formulation is obtained and through a fixed point theorem the existence ...
Average-case complexity of the Euclidean algorithm with a fixed polynomial over a finite field
(Cambridge University Press, 2021-07-06)
We analyse the behaviour of the Euclidean algorithm applied to pairs (g,f) of univariate nonconstant polynomials over a finite field Fq of q elements when the highest degree polynomial g is fixed. Considering all the ...
