Measure Theory On Time Scales
Associated with every time scale is a natural measure defined via
where denotes Lebesgue measure and is the backward shift operator defined on . The delta integral turns out to be the usual Lebesgue–Stieltjes integral with respect to this measure
and the delta derivative turns out to be the Radon–Nikodym derivative with respect to this measure

Famous quotes containing the words measure, theory, time and/or scales:
“One measure of a civilization, either of an age or of a single individual, is what that age or person really wishes to do. A mans hope measures his civilization. The attainability of the hope measures, or may measure, the civilization of his nation and time.”
—Ezra Pound (18851972)
“Lucretius
Sings his great theory of natural origins and of wise conduct; Plato
smiling carves dreams, bright cells
Of incorruptible wax to hive the Greek honey.”
—Robinson Jeffers (18871962)
“Now the hungry lion roars,
And the wolf behowls the moon;
Whilst the heavy ploughman snores,
All with weary task fordone.
Now the wasted brands do glow,
Whilst the screech-owl, screeching loud,
Puts the wretch that lies in woe
In remembrance of a shroud.
Now it is the time of night,
That the graves, all gaping wide,
Every one lets forth his sprite,
In the church-way paths to glide:”
—William Shakespeare (15641616)
“For these have governed in our lives,
And see how men have warred.
The Cross, the Crown, the Scales may all
As well have been the Sword.”
—Robert Frost (18741963)
