The role of the subsurfaces isplayed by a collection of convex subcomplexes called a \emph{factorsystem}, and the role of the curve graph is...

We give severalapplications of this result; for example:\begin{enumerate}\item We build a closed three-dimensional m...

We define a (relative) slender JSJ hierarchy for(almost) finitely presented groups and show that it is finite,provided the group in question doesn'...

Moreover,each of these manifolds admits a unique genus-two trise...

Weconstruct a scanning map'' which compares this space to the space ofsections of a certain fibre bundle over $M$ associated to its tangentbundle, and sho...

By working with{$\...  作者：John Etnyre , David Vela-Vick , Rumen Zarev 来源：[J].Geometry & Topology(IF 0.974), 2017, Vol.21 (3), pp.1469-1582MSP 摘要：\vspace{-8pt}Using contact-geometric techniques and sutured Floer homology,we present an alternate formulation of the minus and plusversions of knot Floer homology. We further show how naturalconstructions in the realm of contact geometry give rise tomuch of the formal structure ...  作者：Stefan Buschenhenke , Detlef Müller , Ana Vargas 来源：[J].Analysis & PDE, 2017, Vol.10 (4), pp.817-891MSP 摘要：The problem of$L^q(\mathbb{R}^3)\to L^2(S)$Fourier restriction estimates forsmooth hypersurfaces$S$of finite type in$\mathbb{R}^3$is by now very wellunderstood for a large class of hypersurfaces, including all analyticones. In this article, we take up the study of more gene...  作者：Giulio Romani 来源：[J].Analysis & PDE, 2017, Vol.10 (4), pp.943-982MSP 摘要：We study the ground states of the following generalization of theKirchhoff--Love functional,$J_\sigma(u)=\int_\Omega\frac{(\Delta u)^2}{2} -(1-\sigma)\!\int_\Omega \det(\nabla^2u)-\int_\Omega F(x,u),$where$\Omega$is a bounded convex domain in$\mathbb{R}^2$with$C^{1,1}\$boun...
