    Existing climatological ionosphere models, for example, GISM, SCIONAV, WBMOD, and STIPEE, have known limitations that prevent their wide use. In the framework of ESA study “Radio Climatology Models of the Ionosphere: Status ...
  • A fractional Michael–Simon Sobolev inequality on convex hypersurfaces 

    Cabré Vilagut, Xavier; Cozzi, Matteo; Csató, Gyula (Elsevier, 2023-01-01)
    Part of book or chapter of book / Nautical chart
    Open Access
    The classical Michael–Simon and Allard inequality is a Sobolev inequality for functions defined on a submanifold of Euclidean space. It is governed by a universal constant independent of the manifold, thanks to an additional ...
  • All power structures are achievable in basic weighted games 

    Freixas Bosch, Josep; Pons Vallès, Montserrat (Springer, 2023-04-09)
    Part of book or chapter of book
    Restricted access - publisher's policy
    A major problem in decision making is designing voting systems that are as simple as possible and able to reflect a given hierarchy of power of its members. It is known that in the class of weighted games all hierarchies ...
  • Tutte uniqueness and Tutte equivalence 

    Bonin, Joseph E.; Mier Vinué, Anna de (Chapman & Hall/CRC, 2022-07-07)
    Part of book or chapter of book
    Restricted access - publisher's policy
    This chapter considers graphs or matroids that have the same Tutte polynomial, as well as graphs or matroids that, up to isomorphism, are distinguished from all others by their Tutte polynomial. We call the former Tutte ...
  • The decline of the Buchholz tiebreaker system: a preferable alternative 

    Freixas Bosch, Josep (Springer, 2023-01-20)
    Part of book or chapter of book
    Restricted access - publisher's policy
    We propose a simple method of undoing tiebreaks in sport competitions with a large number of competitors and relatively small number of rounds of competition. Such methods are common in many games including Chess, Go, ...
  • An approximate structure theorem for small sumsets 

    Campos, Marcelo; Coulson, Matthew John; Serra Albó, Oriol; Wötzel, Maximilian (Birkhäuser, 2021-08-24)
    Part of book or chapter of book
    Open Access
    Let A and B be randomly chosen s-subsets of the first n integers such that their sumset A+B has size at most Ks. We show that asymptotically almost surely A and B are almost fully contained in arithmetic progressions PA ...

    Álvarez Montaner, Josep; Jeffries, Jack; Núñez-Betancourt, Luis (Springer Nature, 2022-02-23)
    Part of book or chapter of book
    Restricted access - publisher's policy
    This is an expository survey on the theory of Bernstein-Sato polynomials with special emphasis in its recent developments and its importance in commutative algebra

    Part of book or chapter of book
    Open Access
    This paper proposes a way of approximating the solution of partial differential equations (PDE) using Deep Neural Networks (DNN) based on Keras and TensorFlow, that is capable of running on a conventional laptop, which is ...

    Part of book or chapter of book
    Restricted access - publisher's policy
    A well-known conjecture by Lovász and Plummer from the 1970s asserting that a bridgeless cubic graph has exponentially many perfect matchings was solved in the affirmative by Esperet et al. (Adv. Math. 2011). On the other ...
