Finite topology self-translating surfaces for the mean curvature flow in R-3
(2017)
Finite topology self-translating surfaces for the mean curvature flow constitute a key element in the analysis of Type II singularities from a compact surface because they arise as limits after suitable blow-up scalings ...
Nonlocal Delaunay surfaces
(2016)
We construct codimension 1 surfaces of any dimension that minimize a periodic nonlocal perimeter functional among surfaces that are periodic, cylindrically symmetric and decreasing. These surfaces may be seen as a nonlocal ...
The Craighero-Gattazzo surface is simply connected
(2017)
We show that the Craighero-Gattazzo surface, the minimal resolution of an explicit complex quintic surface with four elliptic singularities, is simply connected. This was conjectured by Dolgachev and Werner, who proved ...
On Z/3-Godeaux Surfaces
(2018)
We prove that Godeaux-Reid surfaces with torsion group Z/3 have topological fundamental group Z/3. For this purpose, we describe degenerations to stable KSBA surfaces with one 1/4 (1, 1) singularity, whose minimal resolution ...
Nonlocal s-minimal surfaces and Lawson cones
(2018)
The nonlocal s-fractional minimal surface equation for Sigma = partial derivative E where E is an open set in R-N is given by H-Sigma(s)(p) := integral(RN) chi E(x) - chi E-c(x)/vertical bar x - p vertical bar N + s dx = ...
Copper-polymer nanocomposites: An excellent and cost-effective biocide for use on antibacterial surfaces
(2016)
The development of polymer nanocomposites with antimicrobial properties has been a key factor for controlling or inhibiting the growth of microorganisms and preventing foodborne diseases and nosocomial infections. Commercially ...
The Appearance of Pitting on Thermally Grown Aluminum Oxide caused by Surface Segregation of Fe Impurities from the Bulk
(2016)
The oxidation of 99 wt.-% purity (low purity - main impurities were Fe and Si) and 99.999 wt.-% purity (high purity) Al foil was studied using a thermo-gravimetric method. The Al oxide was characterized with several ...
Multiterminal conductance at the surface of aWeyl semimetal
(2018)
Weyl semimetals are a new paradigmatic topological phase of matter featuring a gapless spectrum. One of its most distinctive features is the presence of Fermi arc surface states. Here, we report on atomistic simulations ...
Analysis on the stability of in-surface magnetic configurations in toroidal nanoshells
(2019)
Curvature of nanomagnets can be used to induce chiral textures in the magnetization field. Here we perform analytical calculations and micromagnetic simulations aiming to analyze the stability of in-surface magnetization ...
Serrin's overdetermined problem and constant mean curvature surfaces
(2015)
For all N >= 9, we find smooth entire epigraphs in R-N, namely, smooth domains of the form Omega := {x is an element of R-N broken vertical bar X-N broken vertical bar > F(X-1, . . . , X-N-1)}, which are not half-spaces ...
