Approximate solution of dual integral equations
We study dual integral equations which appear in formulation of the potential distribution of an electrified plate with mixed boundary conditions. These equations will be converted to a system of singular integral equations with Cauchy type kernels. Using Chebyshev polynomials, we propose a method to approximate the solution of Cauchy type singular integral equation which will ...
متن کاملDual Integral Equations—revisited
Dual integral equations with trigonometric kernel are reinvestigated here for a solution. The behaviour of one of the integrals at the end points of the interval complementary to the one in which it is defined plays the key role in determining the solution of the dual integral equations. The solution of the dual integral equations is then applied to find an exact solution of the water wave scat...
متن کاملOn totally dual integral systems
Let A be a rational (m x n)-matrix and b be a rational m-vector. The linear system Ax< b is said to be totally dual integral (TDI) if for all integer n-vectors c, the linear program min{b’v: A’y= c; yr 0} has an integer-valued optimum solution if it has an optimum solution. The contents of this paper can be divided into three parts: First of all an attempt is made to characterize special classe...

متن کاملRecognizing Totally Dual Integral Systems is Hard
These are notes about Ding, Feng and Zang’s proof [5]. The proof of their result is not new, the only difference with them is the starting point: we work directly on their gadget graph encoding a SAT problem and not on more general graphs. This allows to shortcut some parts of the original proof that become superfluous. After proving their theorem I clarify some points about total dual integral...
