Subject: Question regarding hard boundary conditions

Dear Colleagues,

I am searching for approximate solution (numerical, analytical,
numerical-analytical) to the following problem:
$u_{xx}+u_{yy}=0$ in $D=[a,b] \times [c,d]$
(that is, 2D Laplace equation in the rectangle),
$(u_x)^2+(u_y)^2 =(\cosh u)^2$ on $\delta D$
(that is, a complex combination of the partial derivatives and
function values on the rectangle boundary).

Any help (suggestion of a method of solution, indication of a
reference or numerical algorithm) is greatly appreciated.

Sincerely,
Andrei Bourchtein

Subject: Jacobi-Davidson Gateway

Dear colleagues,

The Jacobi-Davidson method, proposed by Gerard Sleijpen and
Henk van der Vorst in 1996, is often a competitive eigensolver,
in particular when interior eigenvalues are sought, a
preconditioner for the matrix is available, or generalized
eigenproblems are considered.

The Jacobi-Davidson Gateway
http://www.win.tue.nl/casa/research/topics/jd/

a web site that presents
- a one-page overview of the method;
- a bibliography with links to papers;
- a list of researchers active in this field;
- a catalog of publicly available Jacobi-Davidson software; and
- a list of applications where the JD method has been used.

"Ten digits, Five seconds, And just one page", in his essay:

which compares code to poetry. Thus, the following "code"
"computes" pi to 33 digits (1/3 of a 100-digit challenge),
can be read in about 40 seconds, and fits on half a page.

Each line has a number of syllables equal to a digit
of pi. The angst comes when the poem itself wonders
what to do with the first zero digit ...
