Considering the Bethe‐Salpeter equation as a relativistic equation, we have studied the free particle Green's functions for unequal mass scalar bosons, interacting via a translationally invariant ...

Google on Wednesday (12 November) featured a special Doodle celebrating the quadratic equation, one of mathematics' most fundamental formulas that has shaped everything from engineering to economics.

摘要：The KP equation is a nonlinear dispersive wave equation in 2+1dimension. The equation admits several different types of solutions, such as quasi-periodic solutions and soliton solutions. In this ...

Is it possible to create a macro with new functions that can be used in SOLIDWORKS equations? For example, I would like to use the "LEFT()" function from Excel so I can retrieve the first characters ...

Because of the relatively long growing cycle and the high cost of research into turkey production and nutrition, the potential benefits from modelling growth in this avian species are considerable.

In this paper, we define some non-elementary amplitude functions that are giving solutions to some second-order nonlinear ODEs with forcing term and systems of ODEs with chaotic behavior, such as the ...

The paper discusses the solution of a simple kinetic equation of the type used for the computation of the change of the chemical composition in stars like the Sun. Starting from the standard form of ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...
