Geometric shape of invariant manifolds for a class of stochastic partial differential equations
Stochastic partial differential equation invariant manifolds geometric shape
2010/12/6
Invariant manifolds play an important role in the study of the qualitative dynamical behaviors for nonlinear stochastic partial differential equations. However, the geometric shape of
these manifolds...
Symmetric quivers, invariant theory, and saturation theorems for the classical groups
Symmetric quivers invariant theory saturation theorems for the classical groups
2010/12/7
Let G denote either a special orthogonal group or a symplectic group defined over the complex
numbers. We prove the following saturation result for G: given dominant weights λ1, . . . , λr
such that...
Automorphism group and ad-invariant metric on all six dimensional solvable real Lie algebras
Automorphism group ad-invariant metric all six dimensional solvable real Lie algebras
2010/11/30
Using adjoint representation of Lie algebras, we calculate the automorphism group and ad-invariant metric on six dimensional solvable real Lie algebras with 5, 4 and 3 dimensional nilradicals.

Singular spectral shift Pushnitski $\mu$-invariant
2010/12/8
In this paper it is shown that in case of trace class perturbations the singular part of Pushnitski μ -invariant does not depend on the angle variable. This gives an alternative proof of integer-value...
Some Results on the Solutions of Caputo Fractional Linear Time-Invariant Systems of any order with Internal Point Delays
Caputo fractional calculus Riemann- Liouville fractional calculus Positive solutions and systems
2010/12/9
This paper is devoted to the investigation of the nonnegative solutions and the stability and asymptotic properties of the solutions of fractional differential dynamic systems involving delayed dynami...
Motivic invariant of real polynomial functions and Newton polyhedron
Zeta functions virtual Betti numbers blow-Nash equivalence
2010/12/1
We propose a computation of real motivic zeta functions for real polynomial functions, using Newton polyhedron. As a consequence we show that the weights are blow-Nash invariants of convenient weighte...

The $\star$-operator and Invariant Subtraction Games
Beatty sequence Complementary sequences Dual game
2010/12/9
We study 2-player impartial games, so called invariant subtraction games, of the type, given a set of allowed moves the players take turn in moving one single piece on a large Chess board towards the ...
A poset has the non-messing-up property if it has two covering sets of disjoint saturated chains so that for any labeling of the poset, sorting the labels along one set of chains and then sorting the ...
We consider the Yamabe invariant of a compact orbifold with finitely many singular points. We prove a fundamental inequality for the estimate of the invariant from above, which also includes a criteri...
A complete locally convex space of countable dimension admitting an operator with no invariant subspaces
Cyclic operators invariant subspaces topological vector spaces
2010/12/6
We construct a complete locally convex topological vector space X of countable algebraic dimension and a continuous linear operator T : X → X such that T has no non-trivial closed invariant subspaces.
We exhibit an encoding of knots into processes in the -calculus such that knots are ambient isotopic if and only their encodings are weakly bisimilar.

2010/12/16
We study in detail the structure of phase space in the neighborhood of stable periodic orbits in a rotating 3D potential of galactic type.We have used the color and rotation method to investigate the ...

2010/12/8
We derive a formula for the ¯μ–invariant of a Seifert fibered homology sphere in terms of the –invariant of its Dirac operator. As a consequence, we obtain a vanishing result for the index of ce...
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
2010/12/20
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. The structur and cosmo...
