The structure and evolution of confined tori near a Hamiltonian Hopf Bifurcation
Chaos and Dynamical Systems 4D surfaces of section Hopf Bifurcation
2010/12/28
We study the orbital behavior at the neighborhood of complex unstable periodic orbits in a 3D
autonomous Hamiltonian system of galactic type. At a transition of a family of periodic orbits
from stab...
Small time asymptotics for stochastic evolution equations
Stochastic partial differential equations small time asymp-totics
2011/1/18
We obtain a large deviation principle describing the small time asymp-totics of the solution of a stochastic evolution equation with multiplicative noise. Our assumptions are a condition on the linear...

Schramm Loewner Evolution Liouville Quantum Gravity
2011/2/24
We conformally weld (via “quantum zipping”) two boundary arcs of a Liouville quantum gravity
random surface to generate a random curve called the Schramm-Loewner evolution (SLE). We develop a theory ...

2011/2/24
In these notes we review some recent results concerning the derivation of effective
equations from first principle quantum dynamics. In particular, we discuss the derivation
of the semi-relativistic...

2010/12/28
The analysis of evolution equations such as ordinary or partial differential equations
often splits into two different directions. One either makes minimal assumptions about
their structure and trie...

Loewner Theory in annulus I: evolution families and differential equations
Loewner Theory differential equations
2010/11/23
Loewner Theory, based on dynamical viewpoint, is a powerful tool in Complex Analysis, which plays a crucial role in such important achievements as the proof of famous Bieberbach's conjecture and well...
Time-Evolution of a Fractal Distribution: Particle Concentrations in Free-Surface Turbulence
Fluid Dynamics (physics.flu-dyn) Chaotic Dynamics (nlin.CD)
2010/11/11
Steady-state turbulence is generated in a tank of water and the trajectories of particles forming a compressible system on the surface are tracked in time. The initial uniformly distributed floating p...

Mathematical Physics (math-ph) Exactly Solvable and Integrable Systems (nlin.SI)
2010/11/10
By generating function based on the Jackson's q-exponential function and standard exponential function, we introduce a new q-analogue of Hermite and Kampe-de Feriet polynomials. In contrast to standar...

2010/11/10
We investigate the long time stability of the Sun--Jupiter--Saturn--Uranus system by considering the planar, secular model. Our method may be considered as an extension of Lagrange's theory for the se...
