We are looking for someone who has a copy of the book and who would like to donate it to SIAM--we will have to cut and paste the pages. In exchange, SIAM will give two complimentary copies of the new edition. Please contact Vickie Kearn, Publisher, SIAM, 3600 University City Science Center, Philadelphia, PA 19104-2688; e-mail: kearn@siam.org. Thank you very much. ------------------------------ From: Jim Epperson Date: Wed, 15 Feb 1995 09:57:53 -0600 (CST) Subject: Sideways Heat Equation A colleague and I are studying what might be called the "sideways" heat equation: no initial data, ordinary boundary data at one end of the spatial interval, overdetermined data (fcn & deriv) at the other end. We are aware of two papers on numerical solution of this problem, one by Ewing and Falk in Math. Comp.(1979), and one by Monk in SIAM J. Num. Anal.(1986). Is anyone aware of more recent work on this problem, especially numerical methods? We have a decently working code, but before we invest too much time we would like to know if we are re-inventing the wheel here. Jim Epperson Associate Professor of Mathematics Computer System Administrator epperson@math.uah.edu ------------------------------ From: Jim Epperson Date: Wed, 15 Feb 1995 10:02:33 -0600 (CST) Subject: Integer Solutions to Linear Systems A graph theory colleague has asked about numerical approximation of solutions to linear systems Ax = b, where the solution x is constrained to take on values only in a set of discrete values, typically [0,1], but not always. This isn't an area I have any knowledge of, so I thought I'd post a query. Does anybody have any references for something like this? Jim Epperson Associate Professor of Mathematics Computer System Administrator epperson@math.uah.edu ------------------------------ From: Barry Smith Date: Wed, 15 Feb 1995 20:09:55 -0500 (EST) Subject: Quadratic Programming Code Hi: I am looking for a fast quadratic programming program (preferably in FORTRAN) that can be used to solve very well behaved problems where the number of constraints will almost never exceed 100 or 200. Speed is quite important because the program has to be called many times as part of a statistical estimation problem. I appreciate any assitance you may be able to offer. Barry J.

Congress wanted advice concerning the goals, management, and progress of this five year initiative. The Initiative plans call for federal expenditures of 1.1 billion dollars in 1995. We have completed the Study. You may be particularly interested in Recommendation 3: Continue funding a strong experimental research program in software and algorithms for parallel computing machines. The report is called "Evolving the High Performance Computing and Communications Initiative to support the Nation's Information Infrastructure" It should be available from the National Academy Press in Washington, D.C. in a few weeks. I do not know what its price will be. To order, I suggest you call the National Academy Press. The main number for the Academy is (202) 334-2000. The Study was done under the aegis of the Computer Science and Telecommunications Board. For information on ordering the Study, you can also contact Leslie Wade, a member of the Board's staff. Her address is lwade@nas.edu ------------------------------ From: Claude Brezinski Date: Thu, 16 Feb 1995 16:43:56 +0100 Subject: Formal Orthogonal Polynomials Formal Orthogonal Polynomials The connection between formal orthogonal polynomials (FOP), a generalization of the usual ones, and the Lanczos' method for solving systems of linear equations is known since Lanczos own papers of 1950 and 1952. Nowadays, more and more people working on Lanczos and affiliated methods refer to FOP. I would like to point out that FOP are well-known for a long time, for instance, to those working on Pad\'e approximants and continued fractions. Here are some references, in chronological order, that could be quoted. These polynomials were in fact already treated in Chapter 11 of * H.S. Wall, Analytic Theory of Continued Fractions, Van Nostrand, Princeton, 1948. They can also be found in * E.L. Stiefel, Kernel polynomials in linear algebra and their numerical applications, in "Further Contributions to the Solution of Simultaneous Linear Equations and the Determina- tion of Eigenvalues", NBS Appl. Math. Series, vol. 49, 1958, pp. 1-22. It seems that one of the first papers entirely devoted to this topics in relation with the Pad\'e table is * P. Wynn, A general system of orthogonal polynomials, Quart. J. Math. Oxford, (2) 18 (1967) 81-96. Then, there are two papers by Gragg * W.B. Gragg, The Pad\'e table and its relation to certain algorithms of numerical analysis, SIAM Rev., 14 (1972) 1-62. * W.B. Gragg, Matrix interpretations and applications of the continued fraction algorithm, Rocky Mt. J. Math., 4 (1974) 213-225. Let me mention my own book on the subject where the connection between FOP, the Lanczos method and the topological epsilon-algorithm is treated in detail * C. Brezinski, Pad\'e-Type Approximation and General Orthogonal Polynomials, ISNM vol. 50, Birkh\"auser, Basel, 1980. The non-definite case was treated in the book by Draux where it seems that the word "formal" first appeared * A. Draux, Polyn\^omes Orthogonaux Formels, Applications, LNM vol. 974, Springer-Verlag, Berlin, 1983. More recently, the algebra of linear functionals on the space of polynomials was formalized by Maroni in a series of papers * P. Maroni, Sur quelques espaces de distributions qui sont des formes lin\'eaires sur l'espace vectoriel des polyn\^omes, in "Polyn\^omes Orthogonaux et Applications", C. Brezinski et al. eds., LNM vol. 1171, Springer-Verlag, Berlin, 1985, pp; 184-194. * P. Maroni, Prol\'egom\`enes \`a l'\'etude des polyn\^omes orthogonaux, Ann. Mat. Pura ed Appl., 149 (1987) 165-184 * P. Maroni, Le calcul des formes lin\'eaires et les polyn\^omes orthogonaux semi-classiques, in "Orthogonal Polynomials and their Applications", M. Alfaro et al. eds., LNM vol. 1329, Springer-Verlag, Berlin, 1988, pp. 279-288. * P. Maroni, Une th\'eorie alg\'ebrique des polyn\^omes orthogonaux, applications aux polyn\^omes semi-classiques, in "Orthogonal Polynomials and their Applications", C. Brezinski et al. eds., J.C. Baltzer, Basel, 1991, pp. 95-130. Biorthogonal polynomials also play a role in some generalizations of the Lanczos method. They can be found in * C. Brezinski, Biorthogonality and its Applications to Numerical Analysis, Marcel Dekker, New York, 1992. For the connection between FOP and the Lanczos method, two papers by Gutknecht should be mentionned * M.H. Gutknecht, A completed theory of the unsymmetric Lanczos process and related algorithms, Part I, SIAM J. Matrix Anal. Appl., 13 (1992) 594-639; Part II, idem, 15 (1994) 15-58. There are, of course, many other sources that could have been quoted but, for length reasons, they have not been given here.
