摘要:A deep analysis of the Lyapunov exponents for stationary sequence of matrices going back to Furstenberg, for more general linear cocycles by Ledrappier, and generalized to the context of non-linear cocycles by Avila and Viana, gives an invariance principle for invariant measures ...

摘要:Let $ K$ be an algebraically closed field of prime characteristic $ p$, let $ N\in \mathbb{N}$, let $ \Phi :\mathbb{G}_m^N\longrightarrow \mathbb{G}_m^N$ be a self-map defined over $ K$, let $ V\subset \mathbb{G}_m^N$ be a curve defined over $ K$, and let $ \alpha \in \mathbb{G}_...

摘要:The 4-dimensional Sklyanin algebras, over $ \mathbb{C}$, $ A(E,\tau )$, are constructed from an elliptic curve $ E$ and a translation automorphism $ \tau $ of $ E$. The Klein vierergruppe $ \Gamma $ acts as graded algebra automorphisms of $ A(E,\tau )$. There is also an action of...

摘要:We strengthen the volume inequalities for $ L_p$ zonoids of even isotropic measures and for their duals, which are originally due to Ball, Barthe, and Lutwak, Yang, and Zhang. The special case $ p=\infty $ yields a stability version of the reverse isoperimetric inequality for cen...

摘要:Using a recent result of Panin and Pimenov we show that several results, as for instance the linkage principle, in the algebraic theory of quadratic forms over fields also hold for quadratic forms over regular semilocal domains which contain a field of characteristic not 2. As an...

摘要:The purpose of this paper is to advance our knowledge of two of the most classic and popular topics in transformation semigroups: automorphisms and the size of minimal generating sets. In order to do this, we examine the $ k$-homogeneous permutation groups (those which act transi...

摘要:Given two cyclic $ A_\infty $-algebras $ A$ and $ B$, in this paper we prove that there exists a cyclic $ A_\infty $-algebra structure on their tensor product $ A\otimes B$ which is unique up to a cyclic $ A_\infty $-quasi-isomorphism. Furthermore, the Kontsevich class of $ A\oti...

摘要:The canonical height associated to a polarized endomorphism of a projective variety, constructed by Call and Silverman and generalizing the Néron-Tate height on a polarized abelian variety, plays an important role in the arithmetic theory of dynamical systems. We generalize ...

摘要:A combinatorial expression for the coefficient of the Schur function $ s_{\lambda }$ in the expansion of the plethysm $ p_{n/d}^d \circ s_{\mu }$ is given for all $ d$ dividing $ n$ for the cases in which $ n=2$ or $ \lambda $ is rectangular. In these cases, the coefficient ...

摘要:At the 1987 Ramanujan Centenary meeting Dyson asked for a coherent group-theoretical structure for Ramanujan's mock theta functions analogous to Hecke's theory of modular forms. Many of Ramanujan's mock theta functions can be written in terms of $ R(\zeta ,q)$, where $ R(z,q)$ is...
