This book offers an application of Sobolev gradient approach to Poisson
Boltzmann system. A detailed description of Sobolev gradient method is
given and its application is demonstrated on the Poisson Boltzmann
system when there are large non-linearities and discontinuities in the
coefficient functions. Poisson Boltzmann is a physical model that
governs the electrostatic potential of macromolecules when immersed in
solvent. It is shown that in some cases Sobolev gradient performs better
in terms of efficiency than other existing fast methods such as
multigrid and Newton's methods. The experiments' results are given in
both finite element and finite difference settings. This book presents a
fine blend of Functional Analysis, Numerical Analysis and Biophysics. It
is the Ph.D. work that Dr. Abdul Majid completed under the supervision
of Dr. Sultan Sial.
