WebNov 1, 2016 · We introduce some Hilbert complexes involving second-order tensors on flat compact manifolds with boundary that describe the kinematics and the kinetics of motion in nonlinear elasticity. We then use the general framework of Hilbert complexes to write Hodge-type and Helmholtz-type orthogonal decompositions for second-order tensors. As … WebApr 10, 2024 · No, there is in general no Fréchet derivative (unless H has dimension 0 ). We will first consider the toy case H = C. Then for the standard scalar product we are asking whether the map f: C → C, z ↦ z 2 is complex differentable (that is what it means for the Fréchet derivative to exist).

Oberwolfach report : Discretization of Hilbert complexes

WebThis report aims to review some progress on discretizing Hilbert complexes. The emphasis is mainly on conforming nite elements on simplices, while other important topics are not covered, e.g., polyhedral elements, virtual elements, isogeometric analysis, nonconforming elements and applications. Hilbert spaces arise naturally and frequently in mathematics and physics, typically as function spaces. Formally, a Hilbert space is a vector space equipped with an inner product that defines a distance function for which the space is a complete metric space. See more In mathematics, Hilbert spaces (named after David Hilbert) allow generalizing the methods of linear algebra and calculus from (finite-dimensional) Euclidean vector spaces to spaces that may be infinite-dimensional. … See more Lebesgue spaces Lebesgue spaces are function spaces associated to measure spaces (X, M, μ), where X is a set, M is a σ-algebra of subsets of X, and μ is a countably additive measure on M. Let L (X, μ) be the space of those complex … See more Pythagorean identity Two vectors u and v in a Hilbert space H are orthogonal when ⟨u, v⟩ = 0.
