Random variables and positive definite Kernels associates with the Schrodinger algebra [PDF]
, 2009 We show that the Feinsilver‐Kocik‐Schott (FKS) kernel for the Schrödinger algebra is not positive definite. We show how the FKS Schrödinger kernel can be reduced to a positive definite one through a restriction of the defining parameters of the ...

Sobolev algebras through heat kernel estimates [PDF]
, 2015 On a doubling metric measure space $(M,d,\mu)$ endowed with a "carr\'e du champ", let $\mathcal{L}$ be the associated Markov generator and $\dot L^{p}_\alpha(M,\mathcal{L},\mu)$ the corresponding homogeneous Sobolev space of order $0 0}$ for the spaces $\

A Primer on Reproducing Kernel Hilbert Spaces [PDF]
Foundations and Trends® in Signal Processing, 2014 Reproducing kernel Hilbert spaces are elucidated without assuming prior familiarity with Hilbert spaces. Compared with extant pedagogic material, greater care is placed on motivating the definition of reproducing kernel Hilbert spaces and explaining when

Group Classification of the Unsteady Axisymmetric Boundary Layer Equation
MathematicsUnsteady equations of flat and axisymmetric boundary layers are considered. For the unsteady axisymmetric boundary layer equation, the problem of group classification is solved. It is shown that the kernel of symmetry operators can be extended by no more

Mapping the risk for transmission of urban schistosomiasis in the Brazilian Northeast
Geospatial Health, 2020 This is an analysis of the risk of schistosomiasis transmission in the city of Recife in the Northeast of Brazil based on the number of schistosomiasis cases (Schistosoma mansoni) registered for the period 2007-2017 together with data resulting from ...

On the heat kernel of the Bergmann metric on algebraic varieties [PDF]
Journal of the American Mathematical Society, 1995 Let \(M\) be an algebraic variety in a complex projective space, and \(\Sigma_M\) the singular set of \(M\). The restriction of the Fubini-Study metric of the projective space to the non-singular part \(M/\Sigma_M\) is called Bergmann metric. This is an incomplete Kähler metric, if \(\Sigma_M\neq \phi\). The authors prove that the Laplacian on \(M\) is

Elliptic Ding-Iohara Algebra and the Free Field Realization of the Elliptic Macdonald Operator [PDF]
, 2013 The Ding-Iohara algebra is a quantum algebra arising from the free field realization of the Macdonald operator. Starting from the elliptic kernel function introduced by Komori, Noumi and Shiraishi, we can define an elliptic analog of the Ding-Iohara ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...
