A refined estimate for the topological degree

Hoài-Minh Nguyên

We sharpen an estimate of [4] for the topological degree of continuous maps from a sphere Sdinto itself in the case d >= 2. This provides the answer for d >= 2 to a question raised by Brezis. The problem is still open for d = 1. (C) 2017 Academie des scien ...

Lyapunov functions and finite time stabilization in optimal time for homogeneous linear and quasilinear hyperbolic systems

Hoài-Minh Nguyên

Hyperbolic systems in one-dimensional space are frequently used in the modeling of many physical systems. In our recent works we introduced time-independent feedbacks leading to finite stabilization in optimal time of homogeneous linear and quasilinear hyp ...

Measurement of the inclusive and differential t(t)over-bar gamma cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at root s=13 TeV

Olivier Martin, Ian Smith, Matthias Finger, Richard Pitts, Miguel Fernández Ruiz, Sun Hee Kim, Jean-François Carlin, Jian Zhao, Arvind Shah, Chao Wang, Melody Swartz, Yi Zhang, Dalziel Joseph Wilson, Hoài-Minh Nguyên, Pedro Camilo de Oliveira e Silva, Alberto Hernando de Castro, João Miguel das Neves Duarte, Rakesh Chawla, Myun Sik Kim, Tian Cheng, Thomas Mountford, Yixing Chen, Ananda Sankar Roy, Varun Sharma, Bertrand François, Josef Andreas Schuler, Aravind Kumar Chandiran, Yogesh Singh Chauhan, Jae-Woo Choi, Jin Won Seo, Joo Yeon Kim, Wei Sun, Xiaoqiang Wang, Kyumin Lee, Muhammad Aiman Bin Rahmanudin Hamdan, Chia-Chun Chen, Randoald Müller, Alexis Kalogeropoulos, Jung Eung Park, Ana Margarida Da Costa Ricardo, Sebastian James Davis, Melissa Catherine Olson, Christoph Ernst René Schäfer, Adam Wade Marcus, Johannes Steen, Adrien Alexis Paul Chauvet, Hoang-Trang Lam, Maria Isabel Cordero Campana, Carlos Andres Peña Reyes, Justin Terence Notz Pekkanen, Cristopher Ariel Zeballos Avila

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e(+/-)mu(-/+), e(+)e(-), or mu(+)mu(-)). The measurement is performed using 138 ...

Two subtle convex nonlocal approximations of the BV-norm

Hoài-Minh Nguyên

Inspired by the BBM formula and by work of G. Leoni and D. Spector, we analyze the asymptotic behavior of two sequences of convex nonlocal functionals (Psi(n)(u)) and (Phi(n)(u)) which converge formally to the BV-norm of u. We show that pointwise convergen ...

Cloaking an arbitrary object via anomalous localized resonance: the cloak is independent of the object

Hoài-Minh Nguyên

n this paper, we present various schemes of cloaking an arbitrary object via anomalous localized resonance and provide their analysis in two and three dimensions. This is a way to cloak an object using negative index materials in which the cloaking device ...

Null-controllability of linear hyperbolic systems in one dimensional space

Hoài-Minh Nguyên

This paper is devoted to the controllability of a general linear hyperbolic system in one space dimension using boundary controls on one side. Under precise and generic assumptions on the boundary conditions on the other side, we previously established the ...

Localized and Complete Resonance in Plasmonic Structures

Hoài-Minh Nguyên

This paper studies a possible connection between the way the time averaged electromagnetic power dissipated into heat blows up and the anomalous localized resonance in plasmonic structures. We show that there is a setting in which the localized resonance t ...

Cloaking using complementary media in the quasistatic regime

Hoài-Minh Nguyên

Cloaking using complementary media was suggested by Lai et al. in [8]. The study of this problem faces two difficulties. Firstly, this problem is unstable since the equations describing the phenomenon have sign changing coefficients, hence the ellipticity ...

Cloaking via anomalous localized resonance. A connection between the localized resonance and the blow up of the power for doubly complementary media

Hoài-Minh Nguyên

This paper is devoted to the study of cloaking via anomalous localized resonance (CALR) in two and three dimensions in the quasistatic regime. Two key figures of CALR are (i) the localized resonance and (ii) the connection between the localized resonance a ...

On the optimal controllability time for linear hyperbolic systems with time-dependent coefficients

Hoài-Minh Nguyên

The optimal time for the controllability of linear hyperbolic systems in one dimensional space with one-side controls has been obtained recently for time-independent coefficients in our previous works. In this paper, we consider linear hyperbolic systems w ...

Cloaking via anomalous localized resonance for doubly complementary media in the finite frequency regime

Hoài-Minh Nguyên

Cloaking a source via anomalous localized resonance (ALR) was discovered by Milton and Nicorovici in [15]. A general setting in which cloaking a source via ALR takes place is the setting of doubly complementary media. This was introduced and studied in [20 ...

Discreteness of interior transmission eigenvalues revisited

Hoài-Minh Nguyên, Quoc Hung Nguyen

This paper is devoted to the discreteness of the transmission eigenvalue problems. It is known that this problem is not self-adjoint and a priori estimates are non-standard and do not hold in general. Two approaches are used. The first one is based on the ...
