| = Yacop/Sage integration = = PAGE NOT FINISHED YET - BE PATIENT PLEASE = Yacop stands for "Yet Another Cohomology Program". It's a package of routines that allow to compute and investigate Steenrod algebra resolutions. The following functions are currently available: * Computatation of a minimal resolution * Graphical user interface (includes creation of postscript charts and SQL-console) * Ext of small modules * Chain maps (includes computation of P^0 and change of algebra maps) Not everything has been thoroughly tested, though. Here's a little TO-DO list * Framework for modules is missing * Regression test suite needs to be created = Installation instructions = == Download the following Sage packages & patches == * tcltk8.5.7 from http://nullhomotopie.de/tcltk8.5.7.spkg * yacop1.0 from http://nullhomotopie.de/yacop1.0.spkg * patch from http://nullhomotopie.de/11803.patch == Install TclTk and recompile pyhon == This is done via the commands * `sage -f -s tcltk8.5.7.spkg` * `sage -f -s python-2.5.2.p9` [Python recompilation is only required because Tcl/Tk was not installed on the official sage-build machine at build time. This can probably not be necessary in the future.] To check whether Tcl/Tk has been succesfully installed, you should try this: {{{ ddd }}} |
