Hi, I'm still thinking about returning to complete a grad. diploma (I have a BSc in CS, with a EE minor). I've got a hankering to do higher math but apparently I need some 2nd yr refresher stuff. And the adv topology, groups and Lie algebras etc aren't available except at 4th yr. And I'm into anthropology and I guess ergodics, cooperative systems, entropy (in all its forms, esp. informational), and modeling. I have a 4th yr paper in parallel processing from the Dip already. Any suggests?
