concepts of essential infimum and essential supremum are related to the notions of infimum and supremum, but adapted to measure theory and functional analysis...

the supremum is also referred to as the least upper bound (or LUB). The infimum is, in a precise sense, dual to the concept of a supremum. Infima and suprema...

for a function (see limit of a function). For a set, they are the infimum and supremum of the set's limit points, respectively. In general, when there are...

valued function equals the supremum of its essential image and the essential infimum equals the infimum of its essential range. Consequently, a function...

of a set, partially ordered by inclusion, for which the supremum is the union and the infimum is the intersection. Another example is given by the natural...

limit infimum and limit supremum of a set sequence always exist and can be used to determine convergence: the limit exists if the limit infimum and limit...

{\mathbb {R} }}} has a supremum and an infimum (the infimum of the empty set is + ∞ {\displaystyle +\infty } , and its supremum is − ∞ {\displaystyle -\infty...

their composition non-Lebesgue-measurable. The (pointwise) supremum, infimum, limit superior, and limit inferior of a sequence (viz., countably many) of real-valued...

between any two points x and y is the infimum of lengths of paths between them. Unlike in a geodesic metric space, the infimum does not have to be attained...

I {\displaystyle I} in its domain is the difference between the supremum and infimum of f {\displaystyle f} : ω f ( I ) = sup x ∈ I f ( x ) − inf x ∈...

then the supremum and infimum are equal to each other and a unique hedging price exists. The upper and lower bounds created by the subhedging and superhedging...

with least element 0 and greatest element 1. The meet a ∧ b and the join a ∨ b of two elements coincide with their infimum and supremum, respectively, with...

{\displaystyle \gamma \operatorname {-essup} d(x,y)} denotes the essential supremum of d ( x , y ) {\displaystyle d(x,y)} with respect to measure γ {\displaystyle...

closure under countable unions and intersections is paramount. Set limits are defined as follows on σ-algebras. The limit supremum or outer limit of a sequence...

A similar Galois connection whose lower adjoint is given by the meet (infimum) operation can be found in any Heyting algebra. Especially, it is present...
