Energy Momentum Tensor and Marginal Deformations in Open String Field Theory [PDF]

, 2004
Marginal boundary deformations in a two dimensional conformal field theory correspond to a family of classical solutions of the equations of motion of open string field theory.

Quantitative relations between short intervals and exceptional sets of cubic Waring-Goldbach problem

Open Mathematics, 2017
In this paper, we are able to prove that almost all integers n satisfying some necessary congruence conditions are the sum of j almost equal prime cubes with j = 7, 8, i.e., N=p13+…+pj3$\begin{array}{} N=p_1^3+ \ldots +p_j^3 \end{array} $ with |pi−(N ...

Asymptotic formulae for partition ranks [PDF]

, 2014
Using an extension of Wright's version of the circle method, we obtain asymptotic formulae for partition ranks similar to formulae for partition cranks which where conjectured by F.

A geometric version of the circle method

, 2020
We develop a geometric version of the circle method and use it to compute the compactly supported cohomology of the space of rational curves through a point on a smooth affine hypersurface of sufficiently low degree.Comment: 49 pages.

Tunneling in cosine potential with periodic boundary conditions [PDF]

, 2013
In this paper we discuss three methods to calculate energy splitting in cosine potential on a circle, Bloch waves, semi--classical approximation and restricted basis approach.

Partitions into three generalized D. H. Lehmer numbers

AIMS Mathematics
In this paper, we derived that a sufficiently large integer $ N $ can always be represented as the sum of three generalized D. H. Lehmer numbers. As a consequence, we deduced Lu and Yi's original result (Monatsh. Math., 159 (2010), 45–58).

On pairs of equations in unlike powers of primes and powers of 2

Open Mathematics, 2017
In this paper, we obtained that when k = 455, every pair of large even integers satisfying some necessary conditions can be represented in the form of a pair of unlike powers of primes and k powers of 2.

Identification of circles from datapoints using Gaussian sums [PDF]

, 2014
We present a pattern recognition method which use datapoints on a plane and estimates the parameters of a circle. MC data are generated in order to test the method's efficiency over noise hits, uncertainty in the hits positions and number of datapoints ...
