Nonexistence of symplectic structures on certain family of 4-manifolds - Jianfeng LIN 林剑锋, Tsinghua (2024-03-08) Web4 de abr. de 2024 · Abstract. In this paper, we study the existence of conformal metrics with constant holomorphic d-scalar curvature and the prescribed holomorphic d-scalar curvature problem on closed, connected almost Hermitian manifolds of dimension n ⩾ 6. In addition, we obtain an application and a variational formula for the associated conformal invariant.

Web1 de nov. de 2016 · We discuss some applications in classical models of population dynamics. Although we focus on monotone maps, many results of the paper can be applied to maps that admit a non-smooth center ... Webcourse, the stabldunstable invariant manifolds that correspond to a single halo orbit are infinite in number, but reside on the surface of a tube.' Nevertheless, continuous computation of individual manifolds using numerical integration is not efficient or even practical for some applications. In the Weboutline of applications is given. 1.1 Invariant Manifolds for Standard Maps a) Maps versus Systems of ODE's Given a system of ordinary differential equations (ODE's), there are usually various ways to attach to this system a map of some Euclidean space into itself.
