162. Eigenvalues Of Laplacian In The L-shaped Domain By A.L. Skorokhodov and A. Knyazev. http://www-math.cudenver.edu/~aknyazev/software/L/

Andrew Knyazev Eigenvalues of Laplacian in the L-shaped domain In the L-shaped region we consider the eigenvalue problem where is the Laplacian and M is a piece-wise constant function M=1 in and M=M1 in We cover with a mesh, uniform in both directions, with the step h = 1/(N+1). We note, that there are N mesh points on Total number of points in our L-shaped domain is 3N**2 + 2N. In the program , where n can be from 3 up to 15. To make n 16 and larger dimensions of most arrays have to be changed. We use the usual five-point approximation of the Laplacian and a one-point approximation of the operator of multiplication by the function M. That gives us the generalized eigenvalue problem we solve using a preconditioned domain decomposition Lanczos method from A. V. Knyazev and A. L. Skorokhodov, The preconditioned gradient-type iterative methods in a subspace for partial generalized symmetric eigenvalue problem, SIAM J. Numerical Analysis, v. 31, 1226, 1994 The convergence of the method is independent of N and usually every iteration gives one correct digit in the eigenvalue. For the particular problem we solve the cost of one iteration is O(N ln N), and it is required to allocate 8N memory units for components of vectors in the method. To get such low requirements we utilize peculiarities of the problem, for example, we use FFT to solve problems on subdomains. The method can be used for general symmetric eigenproblems as well, but then it is more expensive. The following table shows the computed smallest positive eigenvalue for various N (down) and M1 (across):

166. UBASIC Ratherold version (8.74) of this package. http://archives.math.utk.edu/software/msdos/number.theory/ubasic/.html

UBASIC Version 8.74 UBASIC is a BASIC-like environment which is suitable for number theoretic investigations. Version 8 of UBASIC has the high precision real and complex arithmetic (up to 2600 digits) of previous versions, but adds exact rational arithmetic and arithmetic of polynomials with complex, rational, or modulo p coefficients, as well as string handling and limited list handling capabilities. In addition UBASIC has context-sensitive on-line documentation (read ubhelp.doc for information). The file ubhelp.xxx that this uses is ASCII and can be printed for hard copy documentation. (from the documentation) Download ub874.zip [365 KB]. Download the collection of graphics programs, ub874gr.zip [82 KB]. Look at the readme file from the program.

Downloads LOWX is a program to determine all subgroups of up to a given (low) index in a finitely presented group. The program incorporates three adaptations of the low index subgroups algorithm: standard : finding a representative from each conjugacy class of all subgroups. normal : finding normal subgroups only. mixed : finding normal subgroups but with cosets enumerated over an intermediate subgroup. The source code of the most recent version of LOWX can be downloaded here: lowx-0.11.tar.gz It is released under the terms of the GNU General Public License; for details see the file "COPYING" in the source distribution.

173. Software Iterative Methods: GMRESR And BiCGstab(ell) Fortran 77 subroutines by Henk A. van der Vorst for the iterative methods GMRESR and BiCGstab(ell). These are methods for the iterative solution of large and typically sparse systems of linear equations with a nonsymmetric matrix. http://www.math.uu.nl/people/vorst/software.html

GMRESR and BiCGstab(ell) Here you may find Fortran77 subroutines for the iterative methods GMRESR and BiCGstab(ell). These are methods for the iterative solution of large and typically sparse systems of linear equations with a nonsymmetric matrix. The methods have been introduced in the following papers: H.A. Van der Vorst and C. Vuik GMRESR: a Family of Nested GMRES Methods , Numerical Linear Algebra with Applications, Vol.1(4), pp. 369-386, 1994. G.L.G. Sleijpen and D.R. Fokkema BiCGstab(ell) for Linear Equations involving Unsymmetric Matrices with Complex Spectrum ETNA , 1 (1993), pp. 11-32. If you are a user of the Bi-CGSTAB iterative method , please note that BiCGstab(ell=1) will give you the Bi-CGSTAB algorithm. Moreover, this implementation is the so-called "vanilla version" of Bi-CGSTAB/BiCGstab(ell), i.e. it includes two recent important enhancements for improvement of stability and robustness: G.L.G. Sleijpen and H.A. van der Vorst Reliable updated residuals in hybrid Bi-CG methods , Computing 56 (1996), pp. 141-163.
