      If M=(M,∇) is an affine surface, let Q(M):=ker(H+1m−1ρs) be the space of solutions to the quasi-Einstein equation for the crucial eigenvalue. Let M~=(M,∇~) be another affine structure on M which is strongly projectively ...

    • Evolutionary regime transitions in structured populations 

      Alcalde Cuesta, Fernando; González Sequeiros, Pablo; Lozano Rojo, Álvaro (PLOS, 2018)
      The evolutionary dynamics of a finite population where resident individuals are replaced by mutant ones depends on its spatial structure. Usually, the population adopts the form of an undirected graph where the place ...

      Alcalde Cuesta, Fernando; González Sequeiros, Pablo; Lozano Rojo, Álvaro (Nature Publishing Group, 2016-02-10)
      For a network, the accomplishment of its functions despite perturbations is called robustness. Although this property has been extensively studied, in most cases, the network is modified by removing nodes. In our approach, ...

    • Homogeneous and curvature homogeneous Lorentzian critical metrics 

      Brozos Vázquez, Miguel; Caeiro Oliveira, Sandro; García Río, Eduardo (Cambridge University Press, 2022)
      We determine all three-dimensional homogeneous and 1 -curvature homogeneous Lorentzian metrics which are critical for a quadratic curvature functional. As a result, we show that any quadratic curvature functional admits ...
    • Homogeneous generalized Einstein manifolds in dimension four

      We classify homogeneous four-dimensional manifolds satisfying a curvature condition which naturally generalizes the Einstein one. Our work leads to new examples of self-similar solutions of the two-loop renormalization group flow
    • Isoparametric hypersurfaces in Damek–Ricci spaces 

      Díaz Ramos, José Carlos; Domínguez Vázquez, Miguel (Elsevier, 2013-06-01)
      We construct uncountably many isoparametric families of hypersurfaces in Damek-Ricci spaces. We characterize those of them that have constant principal curvatures by means of the new concept of generalized Kähler angle. ...

      Venegas, Pablo; Gómez Pedreira, Dolores; Arrinda, Mikel; Oyarbide, Mikel; Macicior, Haritz; Bermúdez de Castro López-Varela, Alfredo (Elsevier, 2022)
      The goal of this work is first to include a hysteresis model in the classical equivalent circuit model (ECM) for a battery system and then to improve the estimation of the state of charge (SoC) by applying the Extended ...
    • A method for validating Rent’s rule for technological and biological networks 

      Alcalde Cuesta, Fernando; González Sequeiros, Pablo; Lozano Rojo, Álvaro (Springer Nature, 2017-07-14)
      Rent’s rule is empirical power law introduced in an effort to describe and optimize the wiring complexity of computer logic graphs. It is known that brain and neuronal networks also obey Rent’s rule, which is consistent ...

    • A Perturbation of the Dunkl Harmonic Oscillator on the Line 

      Álvarez López, Jesús Antonio; Calaza Cabanas, Manuel; Franco, Carlos (National Academy of Science of Ukraine, 2015)
      Let Jσ be the Dunkl harmonic oscillator on R (σ>−1/2. For 0<u<1 and ξ>0, it is proved that, if σ>u−1/2, then the operator U=Jσ+ξ|x|−2u, with appropriate domain, is essentially self-adjoint in L2(R,|x|2σdx), the Schwartz ...
