On the Characterization of the Fréchet Derivative with Respect to a Lipschitz Domain of the Acoustic Scattered Field [PDF]
, 1999 In this paper, we consider the Fréchet differentiability with respect to a given domain of the solution of direct acoustic scattering problems with sound-soft, sound-hard, or lossy boundary conditions.

A Simple Grid‐Maps Pipeline: Restructured, Accelerated and Upgraded
Computer Graphics Forum, EarlyView.Abstract Grid maps – spatially arranged small multiples – are a powerful tool to show complex geospatial data. Meulemans et al. (2020) introduced a pipeline for computing high‐quality grid maps that are shaped roughly according to their containing geographic outlines.

Relativistic covariance and nonlinear quantum mechanics: Tomonaga-Schwinger analysis
Physics Letters BWe use the Tomonaga–Schwinger (TS) formulation of quantum field theory to determine when state-dependent additions to the local Hamiltonian density (i.e., modifications to linear Schrödinger evolution) violate relativistic covariance.

A Formula for the Fréchet Derivative of a Generalized Matrix Function [PDF]
, 2016 We state and prove an analogue of the Daleckii--Krein theorem, thus obtaining an explicit formula for the Fréchet derivative of generalized matrix functions.

Computer Graphics Forum, EarlyView.We introduce the physically based neural BRDF, a novel continuous representation for material appearance based on neural fields. Our model accurately performs real‐world material reconstruction, generation and editing, while uniquely enhancing the physical accuracy of neural BRDFs via three key aspects: energy conservation, Helmholtz reciprocity and ...

Higher order fréchet derivatives of matrix functions and the level-2 condition number [PDF]
, 2013 © 2014 SIAM.The Fréchet derivative Lf of a matrix function f: ℂn×n → ℂn×n controls the sensitivity of the function to small perturbations in the matrix. While much is known about the properties of Lf and how to compute it, little attention has been given

Single Line Drawing Generation via Semantics‐Driven Optimization
Computer Graphics Forum, EarlyView.We present a method for automatically generating single‐line drawings in vector format, guided by a text prompt or an input image. Our approach leverages score distillation sampling to optimize the parameters of a uniform rational B‐spline (URBS) curve, ensuring that the drawing consists of a single continuous stroke by design.
