These are a few of my favourite maths

(On the melody of "My Favourite Things" from "Sound Of Music".)

Functors, espec'ly of higher dimensions
Infinite spectra of loops and suspensions
A topological theory on strings
These are a few of my favourite things.

Finally grokking the bar resolution
Solving equations by guessing solutions
zero-dimensional Gorenstein rings
These are a few of my favourite things

When a conference,
a real good one, ends
Then I'm feeling sad
But then I remember my favourite things
And then I don't feel so bad

Posing a question without hesitation
Knowing the proof and in four variations
Dreams of the future, what ever it brings
These are a few of my favourite things

When a complex
is too complex
driving me insane
I take a good look at my favourite things
and know this work's not in vain
