Sobolev-Gaffney type inequalities for differential forms on sub-Riemannian contact manifolds with bounded geometry

open access: yesAdvanced Nonlinear Studies, 2022
In this article, we establish a Gaffney type inequality, in Wℓ,p{W}^{\ell ,p}-Sobolev spaces, for differential forms on sub-Riemannian contact manifolds without boundary, having bounded geometry (hence, in particular, we have in mind noncompact manifolds)

Differential forms and Clifford analysis [PDF]

open access: yes, 2016
In this paper we use a calculus of differential forms which is defined using an axiomatic approach. We then define integration of differential forms over chains in a new way and we present a short proof of Stokes' formula using distributional techniques.

Trauma, immigration, and sexual health among Latina women: Implications for maternal–child well‐being and reproductive justice

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 40, Issue 5, Page 640-658, September/October 2019., 2019
ABSTRACT Latina immigrant women are vulnerable to traumatic stress and sexual health disparities. Without autonomy over their reproductive health and related decision‐making, reproductive justice is elusive. We analyzed behavioral health data from 175 Latina immigrant participants (M age = 35; range = 18–64) of the International Latino Research ...

Averages and the $\ell^{q,1}$-cohomology of Heisenberg groups [PDF]

open access: yes, 2019
Averages are invariants defined on the $\ell^1$ cohomology of Lie groups. We prove that they vanish for abelian and Heisenberg groups. This result completes work by other authors and allows to show that the $\ell^1$ cohomology vanishes in these ...

Ar (λ)‐weighted Caccioppoli‐type and Poincaré‐type inequalities for A‐harmonic tensors

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 31, Issue 2, Page 115-122, 2002., 2002
We prove a local version of weighted Caccioppoli‐type inequality, then we prove a version of weighted Poincaré‐type inequality for A‐harmonic tensors both locally and globally. Ar(λ)-weighted Caccioppoli-type and Poincaré-type inequalities for A-harmonic tensors (erratum)dx.doi.org/10.1155 ...

A Test for Differential Flatness by Reduction to Single Input Systems [PDF]

open access: yes, 1995
For nonlinear control systems (p inputs), we present a test for flatness. The method consists of making an initial guess for p-1 of the flat outputs, which may involve parameters still to be determined.

An application of stress energy tensor to the vanishing theorem of differential forms

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 11, Issue 4, Page 675-682, 1988., 1988
The author applies the stress energy of differential forms to study the vanishing theorems of the Liouville type. It is shown that for a large class of underlying manifolds such as the Euclidean n‐space, the complex n‐space, and the complex hyperbolic space form, if any vector bundle valued p‐form with conservative stress energy tensor is of finite ...

An Intrinsic Characterization of Bonnet Surfaces Based on a Closed Differential Ideal [PDF]

open access: yes, 2013
The structure equations for a surface are introduced and two required results based on the Codazzi equations are obtained from them. Important theorems pertaining to isometric surfaces are stated and a theorem of Bonnet is obtained.

Reduced $L_{q,p}$-Cohomology of Some Twisted Products [PDF]

open access: yes, 2015
Vanishing results for reduced $L_{p,q}$-cohomology are established in the case of twisted products, which are a~generalization of warped products. Only the case $q \leq p$ is considered.

On the naturality of the Mathai-Quillen formula

open access: yes, 2009
We give an alternative proof for the Mathai-Quillen formula for a Thom form using its natural behaviour with respect to fiberwise integration.
