Meroño Moreno, Ana Soledad 2023-06-17T17:24:42Z 2023-06-17T17:24:42Z 2019-08-07 https://hdl.handle.net/20.500.14352/17301 This thesis belongs to the area of General Topology and, in particular, to the field of study of uniform spaces. It is divided in three parts where the related topics Bourbaki-completeness and Samuel realcompactification are studied. Many of the results presented here have already been published by the author in the following papers. [GaMe14] M. I. Garrido and A. S. Mero~no, New types of completeness in metric spaces, Ann. Acad.

In addition, new results, originated during the writing process, have been included. In the first part of the thesis we present many results of [GaMe14], [GaMe16] and some of [HoJuMe19]. More precisely, we study Bourbaki-completeness and cofinal Bourbaki-completeness (equivalently uniform strong-paracompactness) of uniform spaces. In particular, we solve several primary problems related to products, subspaces, hyperspaces, metric spaces and fine spaces... Esta tesis pertenece al area de la Topología General y en particular, al campo de estudio de los espacios uniformes. Esta dividida en tres partes donde se estudian los temas relacionados de Bourbaki-completitud y Realcompactificacion de Samuel.

Tambien han sido incluidos resultados nuevos, surgidos durante el proceso de escritura de la tesis. En la primera parte de esta memoria aparecen muchos resultados de los trabajos [GaMe14], [GaMe16] y algunos de [HoJuMe19]. Mas precisamente, estudiamos la Bourbaki-completitud y la cofinal Bourbaki-completitud (equivalentemente, la fuerte paracompacidad uniforme) en los espacios uniformes. En particular, resolvemos varios problemas basicos relacionados con productos, subespacios, hiperespacios, espacios metricos y espacios con la uniformidad fina... eng open access Bourbaki-complete spaces and Samuel realcompactification doctoral thesis
