Functional properties of limits of Sobolev homeomorphisms with integrable distortion

open access: yesСовременная математика: Фундаментальные направления
The functional and geometric properties of limits of homeomorphisms with integrable distortion of domains in Carnot groups are studied. The homeomorphisms belong to Sobolev classes.

Dispersion‐Less Dissipative Soliton Fiber Laser

open access: yesLaser &Photonics Reviews, EarlyView.
A dispersion‐less fiber laser architecture generates high‐energy, pedestal‐free picosecond pulses without resorting to conventional pulse stretching. This energy‐managed laser achieves remarkable flexibility in pulse parameters, delivering up to 0.54 μJ$\mathrm{\mu}\mathrm{J}$ pulses with minimal spectral distortion using standard telecom components ...

Yamabe-Type Equations on Carnot Groups

open access: yesPotential Analysis, 2016
This article is concerned with a class of elliptic equations on Carnot groups depending of one real positive parameter and involving a critical nonlinearity. As a special case of our results we prove the existence of at least one nontrivial solution for a subelliptic critical equation defined on a smooth and bounded domain $D$ of the {Heisenberg group}

Almost uniform domains and Poincaré inequalities

open access: yesTransactions of the London Mathematical Society, 2021
Here we show existence of many subsets of Euclidean spaces that, despite having empty interior, still support Poincaré inequalities with respect to the restricted Lebesgue measure.

Day‐Ahead Optimal Scheduling of Integrated Energy Systems Considering Diversified Hydrogen Utilisation

open access: yesIET Smart Energy Systems, EarlyView.
Integrated energy systems (IES) facilitate multi‐energy complementarity and efficient energy utilization. This study focuses on an IES with electricity, heating, cooling, and hydrogen loads, the proposed method can achieve a balance between system energy consumption, carbon emissions, and operational economy.

Rectifiability in Carnot Groups

open access: yes, 2022
This thesis is devoted to the study of the theory of rectifiability of sets and measures in the non smooth context of Carnot groups. The focus is on the study of the notion of P-rectifiability and its relation with other notions of rectifiability in Carnot groups.

Conformality and Q-harmonicity in Carnot groups

open access: yesDuke Mathematical Journal, 2006
The main theorem of this paper is that 1-quasiconformal maps are smooth in all Carnot groups. This theorem can be used to prove rigidity theorems for quasiconformal maps between open subsets in certain classes of groups without any a priori smoothness assumption.

Infinite-Dimensional Carnot Groups and Gâteaux Differentiability

open access: yesThe Journal of Geometric Analysis, 2019
The article under review contributes to research based around Rademacher's theorem, which states that a Lipschitz mapping between two Euclidean spaces is differentiable almost everywhere with respect to the Lebesgue measure. More specifically, the article joins a flourishing branch of research which has the broad aim of extending Rademacher's theorem ...

c horizontal convexity on Carnot groups

open access: yes, 2010
Given a real-valued function $c$ defined on the cartesian product of a generic Carnot group $\G$ and the first layer $V_1$ of its Lie algebra, we introduce a notion of $c$ horizontal convex ($c$ H-convex) function on $\G$ as the supremum of a suitable family of affine functions; this family is defined pointwisely, and depends strictly on the horizontal
