0. Okay, last post was fun, now let's get into SPECTRAL SEQUENCES, a device to compute #homology groups!

I hope to unfold a little #tootorial' over the easter holidays, in realtime, pasting as I understand things better.

The uplink is a bit shaky here, and the usual disclaimers apply: about me being easily distracted or getting confused. After all, it's what I do until I finally get it!

#geometry -> #topology -> #homology (#spectralSequence)
