An adaptive multiresolution ultraweak discontinuous Galerkin method for nonlinear Schrödinger equations
(Springer, 20210125)This paper develops a highorder adaptive scheme for solving nonlinear Schrödinger equations. The solutions to such equations often exhibit solitary wave and local structures, which make adaptivity essential in improving ... 
The BAyesian STellar algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology
(Oxford University Press, 20210929)We introduce the public version of the BAyesian STellar Algorithm (BASTA), an opensource code written in PYTHON to determine stellar properties based on a set of astrophysical observables. BASTA has been specifically ... 
Development of a neutrino detector capable of operating in space
(Elsevier B.V., 20230201)The vSOL experiment to operate a neutrino detector close to the Sun is building a small test detector to orbit the Earth to test the concept in space. This detector concept is to provide a new way to detect neutrinos ... 
Level sets of potential functions bisecting unbounded quadrilaterals
(Birkhauser, 20221110)We study the mixed Dirichlet–Neumann problem for the Laplace equation in the complement of a bounded convex polygonal quadrilateral in the extended complex plane. The Dirichlet/ Neumann conditions at opposite pairs of sides ... 
A linearised inverse conductivity problem for the Maxwell system at a high frequency
(Elsevier, 20220415)We consider a linearised inverse conductivity problem for electromagnetic waves in a three dimensional bounded domain at a high timeharmonic frequency. Increasing stability bounds for the conductivity coefficient in the ... 
Manifolds with nonnegative curvature operator of the second kind
(World Scientific Publishing Co., 20230113)We investigate the curvature operator of the second kind on Riemannian manifolds and prove several classification results. The first one asserts that a closed Riemannian manifold with threepositive curvature operator of ... 
Models of metalpoor stars with different initial abundances of C, N, O, Mg, and Si. I. Bolometric corrections derived from new MARCS synthetic spectra and their implications for observed colourmagnitude diagrams
(Oxford University Press, 20211104)New, highresolution MARCS synthetic spectra have been calculated for more than a dozen mixtures of the metals allowing, in turn, for variations in C:N:O, [CNO/Fe], and enhanced abundances of C, O, Mg, and Si. Bolometric ... 
NLO multijet merging for Higgs production beyond the VBF approximation
(Springer Nature, 20220813)We present results of the simulation of electroweak Higgs boson production at the Large Hadron Collider using both the NLO multijet merging and NLO matching frameworks provided by the general purpose event generator Herwig ... 
Numerical computation of a preimage domain for an infinite strip with rectilinear slits
(Springer Link, 20230116)Let Ω be the multiply connected domain in the extended complex plane $\overline {\mathbb {C}}$obtained by removing m nonoverlapping rectilinear segments from the infinite strip $S=\{z : \left \text {Im} z\right <\pi ... 
Positive (p,n)intermediate scalar curvature and cobordism
(Elsevier, 20221101)In this paper we consider a wellknown construction due to Gromov and Lawson, Schoen and Yau, Gajer, and Walsh which allows for the extension of a metric of positive scalar curvature over the trace of a surgery in codimension ... 
Some constructions of formally selfadjoint conformally covariant polydifferential operators
(Elsevier, 20220310)We introduce the notion of formally selfadjoint conformally covariant polydifferential operators and give some constructions of families of such operators. In one direction, we show that any homogeneous conformally ... 
The space of positive scalar curvature metrics on a manifold with boundary
(20141112)We study the space of Riemannian metrics with positive scalar curvature on a compact manifold with boundary. These metrics extend a fixed boundary metric and take a product structure on a collar neighbourhood of the boundary. ... 
Strong local nondeterminism and exact modulus of continuity for isotropic Gaussian random fields on compact twopoint homogeneous spaces
(Springer International Publishing, 20230103)This paper is concerned with sample path properties of realvalued isotropic Gaussian fields on compact twopoint homogeneous spaces. In particular, we establish the property of strong local nondeterminism of an isotropic ...
