We study theoretical aspects of step fluctuations on vicinal surfaces by adding conservative white noise to the Burton-Cabrera-Frank model in one spatial dimension. We consider material deposition fro...
Emergence of step flow from an atomistic scheme of epitaxial growth in 1+1 dimensions
step flow atomistic scheme epitaxial growth 1+1 dimensions
2015/10/16
The Burton-Cabrera-Frank (BCF) model for the flow of line defects (steps) on crystal surfaces has offered useful insights into nanostructure evolution. This model has rested on phenomenological ground...
Growth of Sobolev norms in the cubic defocusing nonlinear Schrodinger equation
Sobolev norms cubic defocusing nonlinear Schrodinger equation
2015/9/25
We consider the cubic defocusing nonlinear Schr¨odinger equation in the two dimensional torus. Fix s > 1. Colliander, Keel, Staffilani, Tao and Takaoka proved in [CKS+10] the existence of solutions wi...
We study the abelian sandpile growth model, where n particles are added at the origin on a stable background configuration in Zd. Any site with at least 2d particles then topples by sending one partic...
Determinants of Population Growth in Rajasthan: An Analysis
Determinants of Population Rajasthan Analysis

Rajasthan is the biggest State of India and is currently in the second phase of demographic
transition and is moving towards the third phase of demographic transition with very slow
pace.
Exponential growth of torsion in Abelian coverings
Exponential growth of torsion Abelian coverings
2011/2/22
We show exponential growth of torsion numbers for links whose first nonzero Alexander polynomial has positive logarithmic Mahler measure. This extends a theorem of Silver ndWilliams
to the case of a ...

Let G denote a closed, connected, self adjoint, noncompact subgroup of GL(n,R), and let dR
and dL denote respectively the right and left invariant Riemannian metrics defined by the canonical inner pr...
A mathematical model of social group competition with application to the growth of religious non-affiliation
sociophysics networks religion perturbation theory
2010/12/28
When groups compete for members, the resulting dynamics of human social activity may be un-
derstandable with simple mathematical models. Here, we apply techniques from dynamical systems
and perturb...
The growth rate of symplectic homology and affine varieties
The growth rate symplectic homology affine varieties
2010/11/18
We will show that the cotangent bundle of an integrally hyperbolic manifold is not symplectomorphic to any smooth affine variety. We will also show that the unit cotangent bundle of such a manifold is...
We evaluate the stability analysis results obtained by two different ways: the neoclassical Solow model and the DSSM. We conclude that the most important advantage achieved with the construction of th...
An improved economic growth model with endogenous fertility

This paper generalizes the model introduced by Cai in [5],
where the Cass-Koopmans optimal growth model has been extended to
allow for endogenous fertility choice. A sufficient condition for the exi...

Many questions in macroeconomics lead to random discrete dynamical systems
yt+1 = wi(yt) where the map wi is contractive and it is chosen in a given set
with probability pi. The aim of this paper is...

In an endogenous growth model with marginal product of cap-

show that the economy has a unique balanced growth path (BGP) eq...
