An intrinsic hyperboloid approach for Einstein Klein–Gordon equations [PDF]

open access: yesJournal of Differential Geometry, 2020
In [7] Klainerman introduced the hyperboloidal method to prove the global existence results for nonlinear Klein-Gordon equations by using commuting vector fields. In this paper, we extend the hyperboloidal method from Minkowski space to Lorentzian spacetimes.

Dynamic Instability of Beams Under Tip Follower Forces Using Geometrically Exact, Fully Intrinsic Equations

open access: yesLatin American Journal of Solids and Structures
In this study, the dynamic instability of beams under tip follower forces are considered. The beam is modeled by using the geometrically exact, fully intrinsic beam equations which is subjected to an inclined tip follower force.

Intrinsic energy partition in fission

open access: yesEPJ Web of Conferences, 2013
The intrinsic energy partition between two complementary fission fragments is investigated microscopically. The intrinsic excitation energy of fission fragments is dynamically evaluated in terms of the time-dependent pairing equations.

The Splitting Crank–Nicolson Scheme with Intrinsic Parallelism for Solving Parabolic Equations

open access: yesJournal of Function Spaces, 2020
In this paper, a splitting Crank–Nicolson (SC-N) scheme with intrinsic parallelism is proposed for parabolic equations. The new algorithm splits the Crank–Nicolson scheme into two domain decomposition methods, each one is applied to compute the values at

The Mathematics of Desert: Merit, Fit, and Well-Being

open access: yesPhilosophies, 2022
Here, we argue for a mathematical equation that captures desert. Our procedure consists of setting out principles that a correct equation must satisfy and then arguing that our set of equations satisfies them.

Intrinsic time gravity and the Lichnerowicz–York equation [PDF]

open access: yesClassical and Quantum Gravity, 2013
We investigate the effect on the Hamiltonian structure of general relativity of choosing an intrinsic time to fix the time slicing. 3-covariance with momentum constraint is maintained, but the Hamiltonian constraint is replaced by a dynamical equation for the trace of the momentum.

Bathymetry reconstruction via a time-dependent intrinsic shallow water model [PDF]

open access: yes, 2022
In this thesis, we firstly give a presentation of the state of the art of the bathymetry reconstruction problem. Secondly we introduce, in a geometrical setting, the Shallow water model, known for its many applications (dynamics of the athmosphere ...

Intrinsic noise analyzer:a software package for the exploration of stochastic biochemical kinetics using the system size expansion [PDF]

open access: yes, 2012
The accepted stochastic descriptions of biochemical dynamics under well-mixed conditions are given by the Chemical Master Equation and the Stochastic Simulation Algorithm, which are equivalent.

Geometrically Nonlinear Analysis for Elastic Beam Using Point Interpolation Meshless Method

open access: yesShock and Vibration, 2019
The intrinsic beam theory, as one of the exact beam formulas, is quite suitable to describe large deformation of the flexible curved beam and has been widely used in many engineering applications. Owing to the advantages of the intrinsic beam theory, the
