A Caristi fixed point theorem for complete quasi-metric spaces by using mw-distances

Alegre Gil, Maria Carmen; Marín Molina, Josefa (Babes-Bolyai University, 2018-02-01)

[EN] In this paper we give a quasi-metric version of Caristi's fixed point theorem by using mw-distances. Our theorem generalizes a recent result obtained by Karapinar and Romaguera in [7]
A fixed point theorem for generalized contractions involving w-distances on complete quasi-metric spaces

Alegre Gil, Maria Carmen; Marín Molina, Josefa; Romaguera Bonilla, Salvador (SpringerOpen, 2014-02)

We obtain a fixed point theorem for generalized contractions on complete quasi-metric spaces, which involves w-distances and functions of Meir-Keeler and Jachymski type. Our result generalizes in various directions the ...
ÁLGEBRA LINEAL

Marín Molina, Josefa; Balaguer Beser, Ángel Antonio; Felipe Román, María José; Capilla Romá, Maria Teresa (Editorial Universitat Politècnica de València, 2012-10-18)

Este libro proporciona un marco general para cualquiera que desee introducirse en el estudio del Álgebra lineal. El principal objetivo del texto es presentar de forma sencilla y práctica un material con definiciones, ...
Generalized contractive set-valued maps on complete preordered quasi-metric spaces

Marín Molina, Josefa; Romaguera Bonilla, Salvador; Tirado Peláez, Pedro (Hindawi Publishing Corporation, 2013)

By using a suitable modification of the notion of a -distance we obtain some fixed point results for generalized contractive set-valued maps on complete preordered quasi-metric spaces. We also show that several distinguished ...
MÉTODOS MATEMÁTICOS

Balaguer Beser, Ángel Antonio; Capilla Romá, Maria Teresa; Felipe Román, María José; Marín Molina, Josefa; Monreal Mengual, Llúcia (Editorial Universitat Politècnica de València, 2014-03-25)

La materia de Métodos Matemáticos tiene un carácter de formación básica necesaria en la mayoría de los primeros cursos de ingeniería. En este texto aparecen temas correspondientes a tres partes del conocimiento matemático ...
Modified w-distances on quasi-metric spaces and a fixed point theorem on complete quasi-metric spaces

Alegre Gil, Maria Carmen; Marín Molina, Josefa (Elsevier, 2016-04-15)

[EN] In this paper we introduce the notion of modified w-distance (mw-distance) on a quasi-metric space which generalizes the concept of quasi-metric. We obtain a fixed point theorem for generalized contractions with respect ...
Proceedings of the workshop on applied topological structures. WATS'16

Rodríguez López, Jesús; Marín Molina, Josefa (Editorial Universitat Politècnica de València, 2016-10-20)

General Topology has become one of the fundamental parts of mathematics.Nowadays, as a consequence of an intensive research activity, this mathematical branch has been shown to be very useful in modeling several problems ...

Rodríguez López, Jesús; Marín Molina, Josefa (Editorial Universitat Politècnica de València, 2017-10-23)

General Topology has become one of the fundamental parts of mathematics.Nowadays, as a consequence of an intensive research activity, this mathematical branch has been shown to be very useful in modeling several problems ...
Q-functions on quasimetric spaces and fixed points for multivalued maps

Marín Molina, Josefa; Romaguera Bonilla, Salvador; Tirado Peláez, Pedro (SpringerOpen, 2011)

[EN] We discuss several properties of Q-functions in the sense of Al-Homidan et al.. In particular, we prove that the partial metric induced by any T0 weighted quasipseudometric space is a Q-function and show that both ...
Revisiting Bianchini and Grandolfi Theorem in the Context of Modified omega-Distances

Alegre Gil, Maria Carmen; Karapinar, Erdal; Marín Molina, Josefa; Tirado Peláez, Pedro (Springer-Verlag, 2019-12)

[EN] In this paper, we establish a proof for Bianchini and Grandolfi Theorem in the context of quasi-metric spaces via modified omega-distances. As consequences of our main results, we derive several existing fixed point ...
Transformando Cuádricas Regladas

Marín Molina, Josefa (Universidad Politécnica de Madrid, 2012-10)

Pretendemos en este trabajo demostrar cómo a partir de dos cuádricas regladas clásicas como son el hiperboloide de una hoja y el paroboloide hiperbólico y sus secciones, obtenemos distintas figuras geométricas que se pueden ...
Weakly contractive multivalued maps and w-distanceson complete quasi-metric spaces

Marín Molina, Josefa; Romaguera Bonilla, Salvador; Tirado Peláez, Pedro (SpringerOpen, 2011)

[EN] We obtain versions of the Boyd and Wong fixed point theorem and of the Matkowski fixed point theorem for multivalued maps and w-distances on complete quasi-metric spaces. Our results generalize, in several directions, ...
