Stable discontinuous Galerkin FEM without penalty parameters [PDF]
, 2015 We propose a modified local discontinuous Galerkin (LDG) method for second--order elliptic problems that does not require extrinsic penalization to ensure stability.

Local energy decay for scalar fields on time dependent non-trapping backgrounds [PDF]
American Journal of Mathematics, 2017 :We consider local energy decay estimates for solutions to scalar wave equations on nontrapping asymptotically flat space-times. Our goals are two-fold. First we consider the stationary case, where we can provide a full spectral characterization of local

SCALAR AND VECTOR IN COMPULATION
Открытое образование (Москва), 2016 The article deals with two fundamental data types – scalar and vector (array), without the ability of working with them one cannot solve using computer school or university tasks in mathematics, physics, chemistry and other technical training courses ...

A space for inflections: following up on JMM's special issue on mathematical theories of voice leading [PDF]
, 2013 Journal of Mathematics and Music's recent special issue 7(2) reveals substantial common ground between mathematical theories of harmony advanced by Tymoczko, Hook, Plotkin, and Douthett.

A Splitting Theorem for Scalar Curvature [PDF]
Communications on Pure and Applied Mathematics, 2018 We show that a Riemannian 3‐manifold with nonnegative scalar curvature is flat if it contains an area‐minimizing cylinder. This scalar‐curvature analogue of the classical splitting theorem of J. Cheeger and D. Gromoll (1971) was conjectured by D. Fischer‐

Aperture referral in dioptric systems with stigmatic elements
African Vision and Eye Health, 2012 A previous paper develops the general theory of aperture referral in linear optics and shows how several ostensibly distinct concepts, including the blur patch on the retina, the effective corneal patch, the projective field and the field of view, are ...

Isoperimetry, Scalar Curvature, and Mass in Asymptotically Flat Riemannian 3‐Manifolds [PDF]
Communications on Pure and Applied Mathematics, 2016 Let (M, g) be an asymptotically flat Riemannian 3‐manifold with nonnegative scalar curvature and positive mass. We show that each leaf of the canonical foliation of the end of (M, g) through stable constant mean curvature spheres encloses more volume ...

Quantum Reports, 2020 The mathematical similarities between non-relativistic wavefunction propagation in quantum mechanics and image propagation in scalar diffraction theory are used to develop a novel understanding of time and paths through spacetime as a whole.

Oscillation Properties of Scalar Conservation Laws [PDF]
Communications on Pure and Applied Mathematics, 2017 We obtain several new regularity results for solutions of scalar conservation laws satisfying the genuine nonlinearity condition. We prove that the solutions are continuous outside of the jump set, which is codimension one rectifiable.

Measurement of job motivation in TEDS-M: testing for invariance across countries and cultures
Large-scale Assessments in Education, 2016 The paper presents the challenges of cross-country and cross-cultural research on the motivation to become a mathematics teacher based on data from the “Teacher Education and Development Study in Mathematics (TEDS-M)”.
