Recurrence rate in rapidly mixing dynamical systems
Benoit Saussol
For measure preserving dynamical systems on metric spaces we study the time needed by a typical orbit to return back close to its starting point. We prove that when the decay of co…
Hurwitz action on tuples of Euclidean reflections
Jean Michel
We show that if a tuple of Euclidean reflections has a finite orbit under the Hurwitz action of the Artin braid group, then the group generated by these reflections is finite. Hump…
Degenerations for derived categories
Bernt Tore Jensen, Xiuping Su, Alexander Zimmermann
We propose a theory of degenerations for derived module categories, analogous to degenerations in module varieties for module categories. In particular we define two types of degen…
Homomorphisms of complexes via homologies
Intan Muchtadi-Alamsyah
By Rickard's work, two rings are derived equivalent if there is a tilting complex, constructed from projective modules over the first ring such that the second ring is the endomorp…
Domain enhanced interlayer coupling in ferroelectric/paraelectric superlattices
V. A. Stephanovich, I. A. Luk'yanchuk, M. G. Karkut
We investigate the ferroelectric phase transition and domain formation in a periodic superlattice consisting of alternate ferroelectric (FE) and paraelectric (PE) layers of nanomet…
Subfield symmetric spaces for finite special linear groups
Toshiaki Shoji, Karine Sorlin
Let be a finite reductive group defined over a finite field . In the case where is a special linear group, we compute the multiplicities of irreducible characters of $…
