Inf vs sup

WebbA function u that is measurable on Ω is said to be essentially bounded on Ω if there is a constant K such that u ( x ) ≤ K a.e. on Ω. The greatest lower bound of such constants K is called the essential supremum of u on Ω, and is denoted by ess sup x∈Ω u ( x ) . We denote by L∞ (Ω) the vector space of all functions u that ... http://www.math.clemson.edu/~petersj/Courses/M453/Lectures/L11-LiminfLimsupSeq.pdf
