Co--calibrated $G_2$ structure from cuspidal cubics
cuspidal cubics Differential Geometry Algebraic Geometry
2011/9/6
Abstract: We establish a twistor correspondence between a cuspidal cubic curve in a complex projective plane, and a co-calibrated homogeneous $G_2$ structure on the seven--dimensional parameter space ...
Borel structure of the spectrum of a closed operator

2011/8/29
Abstract: For a linear operator $T$ in a Banach space let $\sigma_p(T)$ denote the point spectrum of $T$, $\sigma_{p[n]}(T)$ for finite $n > 0$ be the set of all $\lambda \in \sigma_p(T)$ such that $\...
A geometric interpretation of the triangulated structure of m-cluster categories
m-cluster categories triangulated structure Auslander-Reiten triangles orbit categories Auslander Reiten quivers
2011/8/25
Abstract: The aim of this note is to answer several open problems arising from the geometric description of the $m$-cluster categories of type $A_n$ and their realization in terms of the $m$-th power ...
Exponential power series, Galois module structure and differential modules
Exponential power series Galois module structure Number Theory
2011/8/26
Abstract: We use new over-convergent p-adic exponential power series, inspired by work of Pulita, to build self-dual normal basis generators for the square root of the inverse different of certain abe...
On the Structure of Compatible Rational Functions
Compatibility conditions compatible rational functions hyperexponential function (q-)hypergeometric term
2013/9/3
A finite number of rational functions are compatible if they satisfy the compatibility conditions of a first-order linear functional system involving differential, shift and q-shift operators. We pres...
Anomalous scaling and generic structure function in turbulence
generic structure function Anomalous scaling exponential self-similar
2011/7/7
We discuss on an example a general mechanism of apparition of anomalous scaling in scale invariant systems via zero modes of a scale invariant operator. We discuss the relevance of such mechanism in t...
Detecting the temporal structure of intermittent phase locking
Detecting temporal structure intermittent phase locking
2011/7/7
This study explores a method to characterize temporal structure of intermittent phase locking in oscillatory systems. When an oscillatory system is in a weakly synchronized regime away from a synchron...
Assessing the consistency of community structure in complex networks
complex networks community structure consistency Assessing
2011/7/6
In recent years, community structure has emerged as a key component of complex network analysis. As more data has been collected, researchers have begun investigating changing community structure acro...
Intrinsic branching structure within random walk on $\mathbb{Z}$
random walk branching process random environment invariant density
2011/1/17
In this paper, we reveal the branching structure for a non-homogeneous random walk with bounded
jumps. The ladder time T1, the first hitting time of [1,∞) by the walk starting from 0, could be expres...
Almost Series-Parallel graphs: structure and colorability
Series-Parallel graphs structure colorability
2011/2/28
The series-parallel (SP) graphs are those containing no topological K4 and are considered trivial.We relax the prohibition distinguishing the SP graphs by forbidding only embeddings of K4 whose edges ...
Self-intersections in combinatorial topology: statistical structure
closed curves surfaces self-intersection central limit theorem Markov chain
2011/1/17
Oriented closed curves on an orientable surface with boundary are described up to continuous deformation by reduced cyclic words in the generators of the fundamental group and their inverses.

2011/1/20
We construct smooth complex projective varieties of dimension 3 to 6 with variations of Hodge structure, by generalizing an example of J. Carlson and C. Simpson in dimension 2. Then, we study some of ...

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...

2011/2/25
We study the C*-algebra crossed product C0(X) ⋊ G of a locally compact group G acting properly on a locally compact Hausdorff space X.Under some mild extra conditions, which are automatic if G i...

2011/1/17
We determine the graded composition multiplicity in the symmetric algebra S•(V ) of the natural GLn(q)-module V , or equivalently in the coinvariant algebra of V ,for a large class of irreducibl...
