The concepts of essential infimum and essential supremum are used in measure theory and functional analysis to extend the idea of infimum and supremum in a way that accounts for sets that may have measure zero. These concepts are particularly useful when dealing with functions that may have discontinuities or singularities on sets of measure zero.
