Establishing Shape Correspondences: A Survey
Computer Graphics Forum, EarlyView.Abstract Shape correspondence between surfaces in 3D is a central problem in geometry processing, concerned with establishing meaningful relations between surfaces. While all correspondence problems share this goal, specific formulations can differ significantly: Downstream applications require certain properties that correspondences must satisfy ...

Multiple valued Jacobi fields [PDF]
Calculus of Variations and Partial Differential Equations, 2019 We develop a multivalued theory for the stability operator of (a constant multiple of) a minimally immersed submanifold $Σ$ of a Riemannian manifold $\mathcal{M}$. We define the multiple valued counterpart of the classical Jacobi fields as the minimizers of the second variation functional defined on a Sobolev space of multiple valued sections of the ...

Differentiable Randers‐Finsler Eikonal Solvers
Computer Graphics Forum, EarlyView.Abstract Fast and differentiable solvers for anisotropic and asymmetric distance fields are a key primitive in geometry processing, enabling gradient‐based optimization over metrics, drift fields, and downstream objectives that depend on geodesic distances and geodesics.

Stability analysis of geodesics in dynamical Chern–Simons black holes: a geometrical perspective
European Physical Journal C: Particles and FieldsWe apply the Kosambi–Cartan–Chern theory to perform an extensive examination of Jacobi stability of geodesics around rotating black hole solutions to dynamical Chern–Simons gravity, a theory that introduces modifications to General Relativity via a ...

上海师范大学学报. 自然科学版, 2015 We study the cosmological inflation models driven by the rolling tachyon field which has a Born-Infeld-type action.We drive the Hamilton-Jacobi equation for the cosmological dynamics of tachyon inflation and the mode equations for the scalar and tensor ...

European Physical Journal C: Particles and Fields, 2020 Obtaining solutions of the Einstein field equations describing spinning compact bodies is typically challenging. The Newman–Janis algorithm provides a procedure to obtain rotating spacetimes from a static, spherically symmetric, seed metric.

Primal SPH Solver for Strongly Coupled Multiphase Simulations with High Density Ratios
Computer Graphics Forum, EarlyView.Abstract In recent years, the Smoothed Particle Hydrodynamics (SPH) approach has been increasingly used for multiphase simulations involving interactions between diverse materials. A critical component of an SPH simulator is the pressure solver, which not only facilitates the simulation of compressible or incompressible fluids but also handles contact ...

Gender, Work &Organization, EarlyView.ABSTRACT Despite women's growing presence in male‐dominated occupations, men remain underrepresented in female‐typed occupations. This imbalance is commonly attributed to three factors: (1) the confinement of female‐typed occupations to a narrow range of stereotypical domains, (2) their lower socioeconomic rewards, and (3) the stigma men face in gender‐

Towards a unified publicly accessible database of avian type specimens
Ibis, EarlyView.Type specimens represent the crucial physical reference for any scientific bird name, but type material is scattered widely across the globe, and there is still no one comprehensive source documenting the presence, status and condition of all avian type specimens, as well as associated information on nomenclature and the validity of individual names ...

Mean Field Game with Delay: A Toy Model
Risks, 2018 We study a toy model of linear-quadratic mean field game with delay. We “lift” the delayed dynamic into an infinite dimensional space, and recast the mean field game system which is made of a forward Kolmogorov equation and a backward ...
