M-affine functions of means with a simple functional weight
(Academic Press Inc Elsevier Science, 2020-07)
Several sufficient conditions are presented in order that the M-affine (continuous) functions corresponding to a (strict continuous) mean M be all affine functions.
A discrete Fourier transform associated with the affine Hecke algebra
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
We introduce an explicit representation of the double affine Hecke algebra (of type A(1)) at q = 1 that gives rise to a periodic counterpart of a well-known Fourier transform associated with the affine Hecke algebra. (C) ...
Unitary representations of affine Hecke algebras related to Macdonald spherical functions
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2012)
For any reduced crystallographic root system, we introduce a unitary representation of the (extended) affine Hecke algebra given by discrete difference-reflection operators acting in a Hilbert space of complex functions ...

M-affine functions composing Sturm–Liouville families
(Springer, 2018-10)
Given an n-variable mean M defined on a real interval I, an M-affine function is a solution to the functional equation [Equation not available: see fulltext.]When M is a quasilinear mean, the set of continuous M-affine ...

Affinity and distance. On the Newtonian structure of some data kernels
(De Gruyter Open Ltd, 2018-02)
Let X be a set. Let K(x, y) > 0 be a measure of the affinity between the data points x and y. We prove that K has the structure of a Newtonian potential K(x, y) = φ(d(x, y)) with φ decreasing and d a quasi-metric on X under ...
Performance enhancement of switched affine systems by switched quadratic Lyapunov functions: Applications in DC-DC converters
(2013-01-01)
This paper proposes design methodologies to include the convergence rate to Switched Affine Systems, intending to reduce the current overshoot in DC-DC converters. The initial step consists in finding Lyapunov matrices for ...
