Graph Theory in Sage from William Stein on Vimeo.
This is a talk about how to create, display, and work with graphs in Sage.
This introduction to Sage is about the big picture: the range of functionality, what the notebook can do for collaboration and students, etc. Karl-Dieter Crisman demonstrates some basic commands, show a few servers, and how Sage has been used for teaching. You'll also learn how to use R in the notebook and how to publish worksheets.
Systems of differential equations can be used to mathematically model the weather, electrical networks, spread of infectious diseases, conventional battles, populations of competing species, and, yes, zombie attacks. This talk looks at some of these models from the computational perspective using the mathematical software Sage.
