Deterministic hierarchical networks
Barrière Figueroa, Eulalia; Comellas Padró, Francesc de Paula; Dalfó Simó, Cristina (2006)
Article
Accés obertIt has recently been shown that many networks associated with complex systems are small-world (they have both a large local clustering and a small average distance and diameter) and they are also scale-free (the degrees ... -

Disease networks identify specific conditions and pleiotropy influencing multimorbidity in the general population
Amell, A.; Roso Llorach, Albert; Palomero, L.; Comellas Padró, Francesc de Paula (Nature, 2018-10-29)
Article
Accés obertMultimorbidity is an emerging topic in public health policy because of its increasing prevalence and socio-economic impact. However, the age- and gender-dependent trends of disease associations at fine resolution, and the ... -
El espectro del digrafo mariposa
Comellas Padró, Francesc de Paula; Fiol Mora, Miquel Àngel; Gimbert, Joan; Mitjana Riera, Margarida (A. Márquez, 2002-09)
Text en actes de congrés
Accés obertLa determinación del espectro de un grafo es de interés por la conexión que los autovalores y sus multiplicidades tienen con invariantes y propiedades topológicas del grafo, como el diámetro, conectividad, expansión, ... -

Farey graphs as models for complex networks
Comellas Padró, Francesc de Paula (2009-08-01)
Article
Accés obertFarey sequences of irreducible fractions between 0 and 1 can be related to graph constructions known as Farey graphs. These graphs were first introduced by Matula and Kornerup in 1979 and further studied by Colbourn in ... -

Matemática discreta
Comellas Padró, Francesc de Paula; Fàbrega Canudas, José; Lladó Sánchez, Ana M.; Serra Albó, Oriol (Edicions UPC, 2001)
Llibre
Accés restringit a la comunitat UPCLa matemàtica discreta és la part de les matemàtiques que tracta de les estructures finites i numerables. Aquesta nova branca de les matemàtiques ha rebut un impuls decisiu amb els progressos de la informàtica i de les ... -
Mean first-passage time for random walks on generalized deterministic recursive trees
Comellas Padró, Francesc de Paula; Miralles de la Asunción, Alicia (2010-01-11)
Report de recerca
Accés obert -
Modeling complex networks with self-similar outerplanar unclustered graphs
Comellas Padró, Francesc de Paula; Miralles de la Asunción, Alicia (2009-01-21)
Article
Accés obertThis paper introduces a family of modular, self-similar, small-world graphs with clustering zero. Relevant properties of this family are comparable to those of some networks associated with technological systems with a low ... -
On the Hierarchical Product of Graphs and the Generalized Binomial Tree
Barrière Figueroa, Eulalia; Comellas Padró, Francesc de Paula; Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (2007-09)
Article
Accés obertIn this paper we follow the study of the hierarchical product of graphs, an operation recently introduced in the context of networks. A well-known example of such a product is the binomial tree which is the (hierarchical) ... -
On the spectra of hypertrees
Barrière Figueroa, Eulalia; Comellas Padró, Francesc de Paula; Dalfó Simó, Cristina; Fiol Mora, Miquel Àngel (2007-05)
Article
Accés obertIn this paper we study the spectral properties of a family of trees characterized by two main features: they are spanning subgraphs of the hypercube, and their vertices bear a high degree of (connectedness) hierarchy. ... -
On the spectra of Markov matrices for weighted Sierpinski graphs
Comellas Padró, Francesc de Paula; Xie, Pinchen; Zhang, Zhongzhi (2016)
Text en actes de congrés
Accés obertRelevant information from networked systems can be obtained by analyzing the spectra of matrices associated to their graph representations. In particular, the eigenvalues and eigenvectors of the Markov matrix and related ... -
On the spectrum of the normalized Laplacian of iterated triangulations of graphs
Xie, Pinchen; Zhang, Zhongzhi; Comellas Padró, Francesc de Paula (2016-01-15)
Article
Accés obertThe eigenvalues of the normalized Laplacian of a graph provide information on its topological and structural characteristics and also on some relevant dynamical aspects, specifically in relation to random walks. In this ... -
Oxidative stress is a central target for physical exercise neuroprotection against pathological brain aging
