Lauro Clariana Ricart (Barcelona, 1842-1916) fue un matemático e ingeniero industrial español. Obtuvo en 1873 la cátedra de matemáticas del Instituto de Tarragona. Ese mismo año se graduó de doctor en Ciencias Exactas. ...
En una serie de recientes trabajos, donde se estudian a fondo muchos problemas esenciales de la moderna teoría de las funciones de dos variables complejas, F. SEVERI ha establecido las bases de una fundamentación geométrica ...
En una serie de Notas y Memorias, el autor de ésta demostró que cuando la serie de Taylor, que representa una función entera u holomorfa en el círculo unidad, es suficiente lagunar, la función toma la totalidad de los ...
En esta memoria, nos proponemos dar alguna contribución al estudio de la aritmética de las extensiones de cuerpos, de números, galoisianas, no abelianas, cuyo grupo de Galois G sea de uno de los tipos siguientes: diedral ...
En este trabajo se definen y estudian los conceptos de H-convexidad y H-conjugación, siendo H una familia de funciones reales de variable real cerrada para el supremo puntual de tal manera que coinciden con los clásicos ...
Se ha desarrollado un modelo galáctico no estacionario con simetria cilíndrica basado en las hipótesis de Chandrasekhar, habiéndose caracterizado las funciones que lo determinan. La forma obtenida para el potencial ha ...
Según un conocido teorema de Wedderburn, toda álgebra normal y simple es el producto directo (tensorial) de un álgebra total de matrices y un álgebra de división. A partir de aquí R. Brauer divide las álgebras normales y ...
[eng] Framed within the areas of algebraic geometry and commutative algebra, this thesis contributes to the study of sheaves and vector bundles on toric varieties. From different perspectives, we take advantage of the ...
[eng] Machine learning has experienced a soar thanks to the proliferation of deep learning based methodologies. 3D vision is one of the many fields that benefited from this trend. Within this domain, I focused my research ...
[eng] Deep Learning (DL) has gained traction in the last years thanks to the exponential increase in compute power. New techniques and methods are published at a daily basis, and records are being set across multiple ...
[eng] The notion of cause and effect is fundamental to our understanding of the real world; ice cream sales correlate with jellyfish stings (both increase during summer), but a ban on ice cream could hardly stop jellyfishes. ...
[eng] As autonomous agents become increasingly sophisticated and we allow them to perform more complex tasks, it is of utmost importance to guarantee that they will act in alignment with human values. This problem has ...
[spa] Las cubiertas del suelo son el resultado de factores naturales, socioeconómicos y de su utilización por parte de las personas en el tiempo y en el espacio. La información sobre las dinámicas del territorio es esencial ...
[eng] During the last few years, AI development in deep learning has been going so fast that even important researchers, politicians, and entrepreneurs are signing petitions to try to slow it down. The newest methods for ...
[eng] The thesis develops an incipient methodology to study bifurcations of invariant curves in one-dimensional and quasiperiodic discrete systems, based on translated curve theorems and KAM theory.The (extended) phase ...
[eng] We study discrete energy minimization problems on two-point homogeneous manifolds. Since finding N-point configurations with optimal energy is highly challenging, recent approaches have involved examining random point ...
[eng] Deep Learning (DL) models have gained extensive attention due to their remarkable performance in a wide range of real-world applications, particularly in computer vision. This achievement, combined with the increase ...
[eng] The field of Artificial Intelligence (AI) has undergone a revolution in recent years with the advent of more efficient computing hardware and well-documented software for model development. Many fields are being ...
[eng] With the aim of creating artificial systems capable of mirroring the nuanced understanding and interpretative powers inherent to human cognition, this thesis embarks on an exploration of the intersection between human ...
