    • openAccess   A Gaussian kernel for Kendall’s space of m-D shapes 

      Gimeno i Garcia, Vicent; Gual-Arnau, Ximo; Ibáñez Gual, Maria Victoria; Simó, Amelia Elsevier ScienceDirect (2023-08-15)
      In this paper, we develop an approach to exploit kernel methods with data lying on the m-D Kendall shape space. When data arise in a finite-dimensional curved Riemannian manifold, as in this case, the usual Euclidean ...

    • openAccess   No-go theorems for photon state transformations in quantum linear optics 

      V. Parellada, Pablo; Gimeno i Garcia, Vicent; Moyano-Fernández, Julio José; Garcia-Escartin, Juan Carlos Elsevier (2023)
      We give a necessary condition for photon state transformations in linear optical setups preserving the total number of photons. From an analysis of the algebra describing the quantum evolution, we find a conserved quantity ...

    • openAccess   Parabolicity of Invariant Surfaces 

      Del Prete, Andrea; Gimeno i Garcia, Vicent Springer (2024-02-22)
      We present a clear and practical way to characterize the parabolicity of a complete immersed surface that is invariant with respect to a Killing vector field of the ambient space.
