On Koopman and Perron-Frobenius operators of random dynamical systems
ESAIM: Proceedings and Surveys, 2014 In this paper, we investigate the Koopman and the Perron-Frobenius operators of random dynamical systems in general setting. Moreover, we give some necessary and sufficient conditions for the existence of invariant densities for the ...

Secure Federated Matrix Factorization [PDF]
IEEE Intelligent Systems, 2019 To protect user privacy and meet law regulations, federated (machine) learning is obtaining vast interests in recent years. The key principle of federated learning is training a machine learning model without needing to know each user’s personal raw ...

Factorization structures with a two-dimensional factor [PDF]
Journal of the London Mathematical Society, 2009 We introduce the notion of quantum duplicates of an (associative, unital) algebra, motivated by the problem of constructing toy-models for quantizations of certain configuration spaces in quantum mechanics. The proposed (algebraic) model relies on the classification of factorization structures with a two-dimensional factor.

Relating Transverse Momentum Dependent and Collinear Factorization Theorems in a Generalized Formalism [PDF]
, 2016 We construct an improved implementation for combining transverse-momentum-dependent (TMD) factorization and collinear factorization. TMD factorization is suitable for low transverse momentum physics, while collinear factorization is suitable for high ...

Factorization of symplectic matrices into elementary factors
Proceedings of the American Mathematical Society, 2020 We prove that a symplectic matrix with entries in a ring with Bass stable rank one can be factored as a product of elementary symplectic matrices. This also holds for null-homotopic symplectic matrices with entries in a Banach algebra or in the ring of complex valued continuous functions on a finite dimensional normal topological space.

Shifted Riccati Procedure: Application to Conformal Barotropic FRW Cosmologies
Symmetry, Integrability and Geometry: Methods and Applications, 2011 In the case of barotropic FRW cosmologies, the Hubble parameter in conformal time is the solution of a simple Riccati equation of constant coefficients.

Factorization theorems for strong maps between matroids of arbitrary cardinality
Open Mathematics, 2016 In this paper we present factorization theorems for strong maps between matroids of arbitrary cardinality. Moreover, we present a new way to prove the factorization theorem for strong maps between finite matroids.
