On a fourth order nonlinear Helmholtz equation [PDF]

open access: yes, 2018
In this paper, we study the mixed dispersion fourth order nonlinear Helmholtz equation $\Delta^2 u -\beta \Delta u + \alpha u= \Gamma|u|^{p-2} u$ in $\mathbb R^N$ for positive, bounded and $\mathbb Z^N$-periodic functions $\Gamma$.

Hilbert spaces and the pair correlation of zeros of the Riemann zeta-function [PDF]

open access: yes, 2013
Montgomery's pair correlation conjecture predicts the asymptotic behavior of the function $N(T,\beta)$ defined to be the number of pairs $\gamma$ and $\gamma'$ of ordinates of nontrivial zeros of the Riemann zeta-function satisfying $00$, using ...

Post-Newtonian parameters gamma and beta of scalar-tensor gravity with a general potential [PDF]

open access: yes, 2013
We calculate the parametrized post-Newtonian parameters $\ensuremath{\gamma}$ and $\ensuremath{\beta}$ for scalar-tensor gravity with a generic coupling function $\ensuremath{\omega}$ and scalar potential $V$ in the Jordan conformal frame in the case of ...

New extension of beta, Gauss and confluent hypergeometric functions

open access: yesCumhuriyet Science Journal, 2021
There are many extensions and generalizations of Gamma and Beta functions in the literature. However, a new extension of the extended Beta function B_(ζ〖, α〗_1)^(α_2;〖 m〗_1,〖 m〗_2 ) (a_1,a_2 ) was introduced and presented here because of its important ...

The Chazy XII Equation and Schwarz Triangle Functions [PDF]

open access: yes, 2017
Dubrovin [Lecture Notes in Math., Vol. 1620, Springer, Berlin, 1996, 120-348] showed that the Chazy XII equation $y'''- 2yy''+3y'^2 = K(6y'-y^2)^2$, $K \in \mathbb{C}$, is equivalent to a projective-invariant equation for an affine connection on a one ...

Beta-gamma system, pure spinors and Hilbert series of arc spaces [PDF]

open access: yes, 2015
Algorithms are presented for calculating the partition function of constrained beta-gamma systems in terms of the generating functions of the individual fields of the theory, the latter obtained as the Hilbert series of the arc space of the algebraic ...

Weak order for the discretization of the stochastic heat equation [PDF]

open access: yes, 2007
In this paper we study the approximation of the distribution of $X_t$ Hilbert--valued stochastic process solution of a linear parabolic stochastic partial differential equation written in an abstract form as $$ dX_t+AX_t dt = Q^{1/2} d W_t, \quad X_0=x ...
