While many variationist studies have investigated phonological aspects of North American French varieties in the last three decades, few have focused on regional varieties of European French until recently. In the present study, I examine the simplification of word-final obstruent-liquid (OL) clusters – e.g. table ‘table’ and autre ‘other’ realized as [tab] and [ot] – in Vimeu French, a region ...

14 We have implemented the Jacobian-free Newton-Krylov (JFNK) method 15 for solving the first-order ice sheet momentum equation in order to improve 16 the numerical performance of the Community Ice Sheet Model (CISM), the 17 land ice component of the Community Earth System Model (CESM). Our 18 JFNK implementation is based on significant re-use of existing code. For ex19 ample, our physics-based...

In this article, we present a model and a denotational semantics for hybrid systems. Our model is designed so that it may be easily used for modeling large, existing embedded applications, which is a first step toward their validation. The discrete subsystem is modeled by a program written in an extension of an imperative language and the continuous subsystem is modeled by differential equation...

We compute the group of Morita self-equivalences (the Picard group) of a Poisson structure on an orientable surface, under the assumption that the degeneracies of the Poisson tensor are linear. The answer involves mapping class groups of surfaces, i.e., groups of isotopy classes of diffeomorphisms. We also show that the Picard group of these structures coincides with the group of outer Poisson ...

Examples 1. A K3 surface of degree two is a double cover of P, ramified in a smooth sextic. K3 surfaces of degree four are smooth quartics in P. A K3 surface of degree six is a smooth complete intersection of a quadric and a cubic in P. And, finally, K3 surfaces of degree eight are smooth complete intersections of three quadrics in P. The Picard group of a K3 surface is isomorphic to Zn where n...

Preface Why we called the class of two-dimensional Shimura varieties, which are not Hilbert modular, "Picard modular surfaces" ? In the mean time the name has been generally accepted, see e.g. Langlands (and others) L-R]. On the one hand Picard worked on special Fuchsian systems of diierential equations; on the other hand Shimura Shi] introduced and investigated moduli spaces of abelian varieti...

A version of the second main theorem of Nevanlinna theory is proved, where the ramification term is replaced by a term depending on a certain composition operator of a meromorphic function of small hyper-order. As a corollary of this result it is shown that if n ∈ N and three distinct values of a meromorphic function f of hyper-order less than 1/n have forward invariant pre-images with respect ...
