WebIn mathematics, the support of a real-valued function is the subset of the function domain containing the elements which are not mapped to zero. If the domain of is a topological space, then the support of is instead defined as the smallest closed set containing all points not mapped to zero. WebFeb 9, 2024 · The essential supremum of f f is the smallest number a∈ ¯R a ∈ ℝ ¯ for which f f only exceeds a a on a set of measure zero. This allows us to generalize the maximum of a function in a useful way. More formally, we define ess supf ess sup f as follows. Let a∈ R a ∈ ℝ, and define. M a = {x:f(x)> a}, M a = { x: f. ⁢.

For example, if S = ( 0, 1), then any b with b ≥ 1 would be an upper bound of S. Furthermore, the fact that b is not an element of the set S is immaterial.
