[sage-devel] Re: grant proposal season

Earlier this year I applied for an ARC Discovery grant for a 4 year 75% Fellowship ( http://www.arc.gov.au/ncgp/dp/dp_default.htm ) to study the relationship between numerical Clifford algebras, compatible discretization and the solution of PDEs, etc. in mathematical physics. Part of this project

[sage-devel] Relationships between exact, approximate linear algebra and multilinear algebras

Hi all, I will be attending Sage Days 10 in Nancy, but am very new to Sage and need some pointers on where to find stuff. Also, I have heard about some recent developments in C++ linear algebra libraries and wonder how this relates to Sage. The most recent development is Matrix Template Library

Hi all, This is just a short me too note. I am also interested in exterior algebras and differential forms in Sage, but am wondering how to incorporate these with Clifford algebras, Dirac operators, and the functional calculus of operators, especially in relation to the algebraic user

Re: [sage-devel] Sage 4.4.1 build failures with gcc 4.4.1 on SUSE 11.2

In the makefile for symmetrica, the -lm has to go after all the .o files that need libm.a or libm.so. This is standard practice for GNU binutils and not a quirk of OpenSUSE, so I don't see why the build should have worked with any other Linux distribution (remember that I have exported
