Analytical Tachyonic Lump Solutions in Open Superstring Field Theory [PDF]

Journal of High Energy Physics, 2005
We construct a classical solution in the GSO(-) sector in the framework of a Wess-Zumino-Witten-like open superstring field theory on a non-BPS D-brane.

String Field Theory Solution for Any Open String Background [PDF]

, 2014
We present an exact solution of open bosonic string field theory which can be used to describe any time-independent open string background. The solution generalizes an earlier construction of Kiermaier, Okawa, and Soler, and assumes the existence of ...

Fractional and semi-local non-Abelian Chern-Simons vortices [PDF]

, 2010
In this paper we study fractional as well as semi-local Chern-Simons vortices in G = U(1) x SO(2M) and G = U(1) x USp(2M) theories. The master equations are solved numerically using appropriate Ansatze for the moduli matrix field.

Abundant analytical solutions for width-Burger equation: M-shaped, multiwave, breathers and their interactions

Boundary Value Problems
In order to better understand nonlinear wave dynamics, we systematically investigate a wide variety of exact solutions for the modified equal width-Burgers equation (mEWBE), revealing new wave patterns. Lump (L), lump with one kink ( L 1 K ) $(L_{1}K)$ ,

D0-brane tension in string field theory

, 2005
We compute the D0-brane tension in string field theory by representing it as a tachyon lump of the D1-brane compactified on a circle of radius $R$. To this aim, we calculate the lump solution in level truncation up to level L=8.

Gravitating $\sigma$ Model Solitons

, 1998
We study axially symmetric static solitons of O(3) nonlinear $\sigma$ model coupled to (2+1)-dimensional anti-de Sitter gravity. The obtained solutions are not self-dual under static metric. The usual regular topological lump solution cannot form a black

Soliton, breather, lump and their interaction solutions of the ( 2+1 $2+1$)-dimensional asymmetrical Nizhnik–Novikov–Veselov equation

Advances in Difference Equations, 2019
In this work, the ( 2+1 $2+1$)-dimensional asymmetrical Nizhnik–Novikov–Veselov equation is investigated. Hirota’s bilinear method is used to determine the N-soliton solutions for this equation, from which the M-lump solutions are obtained by using long ...

Competition for FDI and profit shifting: On the effects of subsidies and tax breaks [PDF]

, 2013
We investigate competition for FDI within a region when a foreign multinational firm can profitably exploit differences in statutory corporate tax rates by shifting taxable profits to lower-tax jurisdictions.

Habit Formation and Labor Supply [PDF]

This paper shows that the combination of habit formation - present consumption creating additional consumption needs in the future - and myopia may explain why some retirees are forced to ‘unretire’, i.e., unexpectedly return to work.

Multi-wave, breather and interaction solutions to (3+1) dimensional Vakhnenko–Parkes equation arising at propagation of high-frequency waves in a relaxing medium

Journal of Taibah University for Science, 2021
In this study, based on the Hirota bilinear form, the exact analytic solutions of the (3 + 1) dimensional Vakhnenko–Parkes equation with various physical properties were constructed with the help of the Maple package program and symbolic computation ...
