Large Scale Structures in Kinetic Gravity Braiding Model
Large Scale Structures Kinetic Gravity Braiding Model
font style='font-size:12px;'>
2010/12/24
We study cosmological consequences of a kinetic braiding model, which is proposed as an alternative to the dark energy model. The kinetic braiding model we study is characterised by a parameter n, wh...
Supersymmetry restoration in lattice formulations of 2D $\mathcal{N}=(2,2)$ WZ model based on the Nicolai map
Supersymmetry restoration lattice formulations

2010/12/24
For lattice formulations of the two-dimensional $\mathcal{N}=(2,2)$ Wess--Zumino (2D $\mathcal{N}=(2,2)$ WZ) model on the basis of the Nicolai map, we show that supersymmetry (SUSY) and other symmetri...
Spin chains with non-diagonal boundaries and trigonometric SOS model with reflecting end
Spin chains non-diagonal boundaries trigonometric SOS model
font style='font-size:12px;'>
2010/12/24
In this paper we consider two a priori very different problems: construction of the eigenstates of the spin chains with non parallel boundary magnetic fields and computation of the partition function ...
Renormalization effects on MSSM from a calculable model of strongly coupled hidden sector
MSSM calculable model
font style='font-size:12px;'>
2010/12/27
We investigate renormalization effects on the low energy mass spectrum of the minimal supersymmetric standard model (MSSM), using a calculable model of strongly coupled hidden sector. We model the hid...

2010/12/24
The mass spectrum of the noncommutative QED in two-dimensional Euclidean R^2 space is derived first in a perturbative approach at one-loop level and then in a nonperturbative approach using the equiv...
Matrix Model and Refined Wall-Crossing Formula
Matrix Model Refined Wall-Crossing Formula
font style='font-size:12px;'>
2010/12/23
In this paper, we show how to get matrix models corresponding to the refined BPS states partition functions of $\mathbb{C}^3$, resolved conifold and $\mathbb{C}^3/\mathbb{Z}_2$ by inserting the ident...
Phase transition of two-dimensional generalized XY model
Phase transition two-dimensional generalized XY model
font style='font-size:12px;'>
2010/11/16
We study the two-dimensional generalized XY model that depends on an integer $q$ by the Monte Carlo method. This model was recently proposed by Romano and Zagrebnov. We find a single Kosterlitz-Thoul...
Nonlinear Density Waves in the Single-Wave Model
Nonlinear Density Waves the Single-Wave Model
font style='font-size:12px;'>
2010/11/16
The single-wave model equations are transformed to an exact hydrodynamic closure by using a class of solutions to the Vlasov equation corresponding to the waterbag model. The warm fluid dynamic equat...

2011/1/7
We use chirally motivated effective meson-baryon potentials to describe the low energy
¯K N data including the characteristics of kaonic hydrogen. Our results are examined in comparison with oth...

AdS_3 Dual for Minimal Model CFTs
font style='font-size:12px;'>
2010/12/21
We propose a duality between the 2d WN minimal models in the large N ’t Hooft limit, and a family of higher spin theories on AdS3. The 2d CFTs can be described as WZW coset models, and include, for N ...
p-values for Model Evaluation

font style='font-size:12px;'>
2010/11/16
Deciding whether a model provides a good description of data is often based on a goodness-of-fit criterion summarized by a p-value. Although there is considerable confusion concerning the meaning of ...
On a class of semi-elliptic diffusion models. Part I: a constructive analytical approach for global existence, densities, and numerical schemes (with applications to the Libor market model)
Degenerate parabolic equations financial derivatives sen-sitivities Monte-Carlo methods

2010/4/27
Computational parsimony makes reduced factor Libor market models popular among practioners. However, value functions and sensitivities of such models are described by degenerate parabolic (i.e. semiel...

2010/4/2
We propose a model based on the primitive system of the Navier-Stokes equations in a bidimensional framework as the $l$ - plane approximation, which allows us to explain the variety of tracks of tropi...
