kernel space

kernel space

The memory used by the operating system, which is protected and cannot be accessed by regular applications. Virtual memory can be used to page some of the kernel in memory to disk. However, there is always a certain part of the kernel that must reside in physical memory at all times and cannot be swapped out. See kernel, user space and virtual memory.

The present method can approximate the solutions and their derivatives at every point of the range of integration; also it has several advantages such that the conditions for determining solutions can be imposed on the reproducing kernel space, the conditions about the nonlinearity of the forcing function f are simple and may include u, [u.sup.i], or any others operator of u, and the iterative sequence [u.sub.n](x) of approximate solutions converges in C to the solution u(x).
