Do you want to learn three counter-examples for mappings that
LOOK LIKE a metric
but
FAIL to have one of the three defining properties (pos. definiteness, symmetry, triangle inequality)?
It's time for our next Functional Analysis Review and learning about PSEUDO-, QUASI-, and SEMI-metrics!
The video will premiere this Sunday at 8PM UTC +1:

I hope to see you there!
