ℒp space #
This file describes properties of almost everywhere strongly measurable functions with finite
p-seminorm, denoted by eLpNorm f p μ and defined for p:ℝ≥0∞ as 0 if p=0,
(∫ ‖f a‖^p ∂μ) ^ (1/p) for 0 < p < ∞ and essSup ‖f‖ μ for p=∞.
The Prop-valued Memℒp f p μ states that a function f : α → E has finite p-seminorm
and is almost everywhere strongly measurable.
Main definitions #
eLpNorm' f p μ:(∫ ‖f a‖^p ∂μ) ^ (1/p)forf : α → Fandp : ℝ, whereαis a measurable space andFis a normed group.eLpNormEssSup f μ: seminorm inℒ∞, equal to the essential supremumessSup ‖f‖ μ.eLpNorm f p μ: forp : ℝ≥0∞, seminorm inℒp, equal to0forp=0, toeLpNorm' f p μfor0 < p < ∞and toeLpNormEssSup f μforp = ∞.Memℒp f p μ: property that the functionfis almost everywhere strongly measurable and has finitep-seminorm for the measureμ(eLpNorm f p μ < ∞)
ℒp seminorm #
We define the ℒp seminorm, denoted by eLpNorm f p μ. For real p, it is given by an integral
formula (for which we use the notation eLpNorm' f p μ), and for p = ∞ it is the essential
supremum (for which we use the notation eLpNormEssSup f μ).
We also define a predicate Memℒp f p μ, requesting that a function is almost everywhere
measurable and has finite eLpNorm f p μ.
This paragraph is devoted to the basic properties of these definitions. It is constructed as
follows: for a given property, we prove it for eLpNorm' and eLpNormEssSup when it makes sense,
deduce it for eLpNorm, and translate it in terms of Memℒp.
