Time-scale Calculus - Measure Theory On Time Scales

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:

    To measure life learn thou betimes, and know
    Toward solid good what leads the nearest way;
    For other things mild Heaven a time ordains,

    And disapproves that care, though wise in show,
    That with superfluous burden loads the day,
    And, when God sends a cheerful hour, refrains.
    John Milton (1608–1674)

    A theory of the middle class: that it is not to be determined by its financial situation but rather by its relation to government. That is, one could shade down from an actual ruling or governing class to a class hopelessly out of relation to government, thinking of gov’t as beyond its control, of itself as wholly controlled by gov’t. Somewhere in between and in gradations is the group that has the sense that gov’t exists for it, and shapes its consciousness accordingly.
    Lionel Trilling (1905–1975)

    Old hippies don’t die, they just lie low until the laughter stops and their time comes round again.
    Joseph Gallivan (b. 1964)

    It cannot but affect our philosophy favorably to be reminded of these shoals of migratory fishes, of salmon, shad, alewives, marsh-bankers, and others, which penetrate up the innumerable rivers of our coast in the spring, even to the interior lakes, their scales gleaming in the sun; and again, of the fry which in still greater numbers wend their way downward to the sea.
    Henry David Thoreau (1817–1862)
