Rectifiability of a class of integralgeometric measures and applications

E Tasso - arXiv preprint arXiv:2206.14044, 2022 - arxiv.org
In this paper we introduce a new class of integralgeometric measures in $\mathbb {R}^ n $,
built upon the idea of slicing, and depending on the dimension $0\leq m\leq n $ and on the …

Compactness of special functions of bounded higher variation

L Ambrosio, F Ghiraldin - Analysis and Geometry in Metric Spaces, 2013 - degruyter.com
Given an open set Ω⊂ R and> 1, we introduce the new spaces GB V (Ω) of Generalized
functions of bounded higher variation and GSB V (Ω) of Generalized special functions of …

[HTML][HTML] Notes on a slice distance for singular Lp-bundles

M Petrache - Journal of Functional Analysis, 2014 - Elsevier
A slice distance for the class of weak abelian L p-bundles in 3 dimensions was introduced in
[20], where it was used to prove the closure of such class of bundles for the weak L p …

Pricing variance swaps on time-changed Markov processes

P Carr, R Lee, M Lorig - SIAM Journal on Financial Mathematics, 2021 - SIAM
We prove that the variance swap rate (fair strike) equals the price of a co-terminal European-
style contract when the underlying is an exponential Markov process, time-changed by an …

On the structure of flat chains modulo p

A Marchese, S Stuvard - Advances in Calculus of Variations, 2018 - degruyter.com
In this paper, we prove that every equivalence class in the quotient group of integral 1-
currents modulo p in Euclidean space contains an integral current, with quantitative …

Variational approximation of a functional of Mumford–Shah type in codimension higher than one

F Ghiraldin - ESAIM: Control, Optimisation and Calculus of …, 2014 - cambridge.org
In this paper we consider a new kind of Mumford–Shah functional E (u, Ω) for maps u: ℝm→
ℝn with m≥ n. The most important novelty is that the energy features a singular set Su of …
