A proof that all Seifert 3-manifold groups and all virtual surface groups are conjugacy separable
Armando Martino
We prove that the fundamental group of any Seifert 3-manifold is conjugacy separable. That is, conjugates may be distinguished in finite quotients or, equivalently, conjugacy class…
Gundy's decomposition for non-commutative martingales and applications
Javier Parcet, Narcisse Randrianantoanina
We provide an analogue of Gundy's decomposition for L1-bounded non-commutative martingales. An important difference from the classical case is that for any L1-bounded non-commutati…
Laplacian operators and Radon transforms on Grassmann graphs
J. M. Marco, J. Parcet
Let be a vector space over a finite field with q elements. Let G denote the general linear group of endomorphisms of and let us consider the left regular representation $ρ:…
Multiresolution approach for period determination on unevenly sampled data
X. Otazu, M. Ribo, J. M. Paredes +2
In this paper we present a multiresolution-based method for period determination that is able to deal with unevenly sampled data. This method allows us to detect superimposed perio…
