Web31 mar. 2024 · The heat equation and heat kernel on Riemannian manifolds have been extensively studied and they serve as fundamental tools in geometric analysis, for example, the seminal work on parabolic Harnack estimates [ 13] by Li and Yau has been applied and generalized in various literature. On the other hand, the fourth-order biharmonic heat … Web30 ian. 2013 · The methods based on heat kernels have been used in areas as diverse as analysis, geometry, and probability, as well as in physics. This book is a comprehensive introduction to heat kernel techniques in the setting of Riemannian manifolds, which inevitably involves analysis of the Laplace-Beltrami operator and the associated heat …
WebA fundamental tool in shape analysis is the virtual embedding of the Riemannian manifold describing the geometry of a shape into Euclidean space. Several methods have been proposed to embed isometric shapes into flat domains, while preserving the distances measured on the manifold. Recently, attention has been given to embedding shapes into … WebThis note is about the heat kernel on a connected sum M of non-compact manifolds M1, M2, . . . ,Mk assuming that one knows enough about the heat kernels for each Mi individually (which is the case when Mi are complete manifolds of non-negative Ricci curvature). We announce here matching uniform upper and lower bounds for the heat kernel on such …

Web14 apr. 2024 · However, GPS can describe only the global properties of a shape model. To depict a shape’s local information, the heat kernel signature (HKS) was proposed by Sun et al. . Assume a heat source μ 0 (x) on the manifold. HKS t (x,y) defines the heat transferred from point x to point y at time t.
