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:

    “Desire is creation, is the magical element in that process. If there were an instrument by which to measure desire, one could foretell achievement.”
    —Willa Cather (1873–1947)

    “It is not enough for theory to describe and analyse, it must itself be an event in the universe it describes. In order to do this theory must partake of and become the acceleration of this logic. It must tear itself from all referents and take pride only in the future. Theory must operate on time at the cost of a deliberate distortion of present reality.”
    —Jean Baudrillard (b. 1929)

    “Pluck down my officers, break my decrees,
    For now a time is come to mock at form.”
    —William Shakespeare (1564–1616)

    “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)
