Scalar curvature rigidity of geodesic balls in S^n [PDF]
arXiv, 2010 In this paper, we prove a scalar curvature rigidity result for geodesic balls in S^n. This result contrasts sharply with the recent counterexamples to Min-Oo's conjecture for the hemisphere (cf. [5]).

Stability estimate for scalar image velocimetry [PDF]
arXiv, 2020 In this paper we analyse the stability of the system of partial differential equations modelling scalar image velocimetry. We first revisit a successful numerical technique to reconstruct velocity vectors ${u}$ from images of a passive scalar field $\psi$ by minimising a cost functional, that penalises the difference between the reconstructed scalar ...

Spin-charge separation for paired Dirac fermions in (1 + 1) dimensions
Journal of High Energy PhysicsWe study Dirac fermions at finite density coupled to a complex pairing field assumed to obey scalar field theory with quartic self-repulsion. The bulk of our work develops the mathematics that elucidates the propagation of fermionic excitations in such ...

Scalar Field Static Spherically Symmetric Solutions in Teleparallel $F(T)$ Gravity [PDF]
Mathematics 2025, 13(6), 1003We investigate in this paper the static radial coordinate-dependent spherically symmetric spacetime in teleparallel $F(T)$ gravity for a scalar field source. We begin by setting the static field equations (FEs) to be solved and solve the conservation laws for scalar field potential solutions.

Analysis of Parallel Montgomery Multiplication in CUDA [PDF]
, 2013 For a given level of security, elliptic curve cryptography (ECC) offers improved efficiency over classic public key implementations. Point multiplication is the most common operation in ECC and, consequently, any significant improvement in perfor- mance ...

Huygens' Principle for the Non-Self-Adjoint Scalar Wave Equation on Petrov type III Space-Times [PDF]
Ann. Inst. Henri Poincare (A) Phys. Theorique 70, 259 (1999), 2005 We prove that if the non-self-adjoint scalar wave equation satisfies Huygens' principle on Petrov type III space-times, then it is equivalent to the conformally invariant scalar wave equation.

Complete Solution of Hadamard's Problem for the Scalar Wave Equation on Petrov type III Space-Times [PDF]
Ann. Inst. Henri Poincare (A) Phys. Theorique 71, 595-620 (1999), 2005 We prove that there are no Petrov type III space-times on which the conformally invariant (self-adjoint) scalar wave equation or the non-self-adjoint scalar wave equation satisfies Huygens' principle.
