Boletín de la Sociedad Española de Cerámica y Vidrio, 2006 The structures of microcline perthites collected from granitic pegmatites have been studied at different observation scales using optical microscopy (OM), X-ray diffraction (XRD), 27Al MASS-NMR spectroscopy, and electron microprobe (EMPA) with Na ...

On a flow of transformations of a Wiener space
, 2011 In this paper, we define, via Fourier transform, an ergodic flow of transformations of a Wiener space which preserves the law of the Ornstein-Uhlenbeck process and which interpolates the iterations of a transformation previously defined by Jeulin and Yor.

A practical guide to characterising ecological coexistence
Biological Reviews, Volume 101, Issue 1, Page 195-220, February 2026.ABSTRACT Coexistence is simultaneously one of the most fundamental concepts of ecology, and one of the most difficult to define. A particular challenge is that, despite a well‐developed body of research, several different schools of thought have developed over the past century, leading to multiple independent, and largely isolated, branches of ...

The modulated ergodic Hilbert transform
Discrete & Continuous Dynamical Systems - S, 2009 In this article we study the ergodic Hilbert transform modulated by bounded sequences. We prove that sequences satisfying some variation conditions and are universally good for ordinary ergodic averages, such as the sequences defined by the Fourier coefficients of $L_p$ functions, are universally good modulating sequences for the ergodic Hilbert ...

Unitary eigenoperators of ergodic transformations
Journal of Functional Analysis, 1980 AbstractIf h is an ergodic transformation defined on a probability space (S, ∑, μ), then a unitary operøtor V: H → H is said to be an eigenoperator of h if there exists a vector-valued solution X: S → H to the equation X(h(·)) = VX(·). We extend to this case some results from the theory of complex eigenvalues for ergodic finite measure preserving ...
