I have also seen
- β used to denote a probability distribution
- πΌ[X] as the expected value of a random variable X
- π_S as an indicator function for a set S (which is denoted as a subscript)
- π as the differential and integral operator denouncing which variable to integrate over πf/πx f(x) or β« f(x) πx
- OscarCunningham 6y agoI've also seen πΈ for affine space, πΉ for the Booleans, π½ for a field, π for a field, π for octonions and π for surreals. I think I've seen π and π for identity matrices and suchlike, and I'm sure π also gets some use.
