Infimum and supremum - Wikipedia
The supremum (abbreviated sup; pl. : suprema) of a subset of a partially ordered set is the least element in that is greater than or equal to each element of if such an element exists . If the supremum of exists, it is unique, and if b is an upper bound of , then the supremum of. is less than or equal to b. en.wikipedia.org

Essential Supremum -- from Wolfram MathWorld
Jan 18, 2024The essential supremum is the proper generalization to measurable functions of the maximum. The technical difference is that the values of a function on a set of measure zero don't affect the essential supremum. Given a measurable function f:X->R, where X is a measure space with measure mu, the essential supremum is the smallest number alpha such that the set {x:f(x)>alpha} has measure zero.

Supremum of supremum... I have $|f(z)|≤|f(0)|≤M_r$ where $M_r$ is the supremum of $|f(z)| : |z|=r$ Can I take the supremum of the inequality and conclude $M_r≤|f(0)|≤M_r$ $\sup\sup(|f(z)|)= \sup M_r=\text{?}$
To be pedantic, you need to take a supremum over a set. Yes, you may conclude $M_r = |f(0)|$. I don't see how this is relevant to a double sup?

Essential infimum and essential supremum - Wikipedia
Definition. As is often the case in measure-theoretic questions, the definition of essential supremum and infimum does not start by asking what a function does at points (that is, the image of ), but rather by asking for the set of points where equals a specific value (that is, the preimage of under ).. Let : be a real valued function defined on a set . The supremum of a function is ...

Supremum Limit -- from Wolfram MathWorld
6 days agoGiven a sequence of real numbers a_n, the supremum limit (also called the limit superior or upper limit), written lim sup and pronounced 'lim-soup,' is the limit of A_n=sup_ (k>=n)a_k as n->infty, where sup_ (x in S)x denotes the supremum. Note that, by definition, A_n is nonincreasing and so either has a limit or tends to -infty.
