Gronwall's Inequality - Integral Form With Locally Finite Measures

Integral Form With Locally Finite Measures

Let I denote an interval of the real line of the form or ) < ∞ for all tI (this is certainly satisfied when μ is a locally finite measure). Assume that u is integrable with respect to μ in the sense that

and that u satisfies the integral inequality

If, in addition,

  • the function α is non-negative or
  • the function tμ is continuous for tI and the function α is integrable with respect to μ in the sense that

then u satisfies Grönwall's inequality

for all tI, where Is,t denotes to open interval (s, t).

Famous quotes containing the words integral, form, locally, finite and/or measures:

    Make the most of your regrets; never smother your sorrow, but tend and cherish it till it come to have a separate and integral interest. To regret deeply is to live afresh.
    Henry David Thoreau (1817–1862)

    The complaint ... about modern steel furniture, modern glass houses, modern red bars and modern streamlined trains and cars is that all these objets modernes, while adequate and amusing in themselves, tend to make the people who use them look dated. It is an honest criticism. The human race has done nothing much about changing its own appearance to conform to the form and texture of its appurtenances.
    —E.B. (Elwyn Brooks)

    To see ourselves as others see us can be eye-opening. To see others as sharing a nature with ourselves is the merest decency. But it is from the far more difficult achievement of seeing ourselves amongst others, as a local example of the forms human life has locally taken, a case among cases, a world among worlds, that the largeness of mind, without which objectivity is self- congratulation and tolerance a sham, comes.
    Clifford Geertz (b. 1926)

    The finite is annihilated in the presence of the infinite, and becomes a pure nothing. So our spirit before God, so our justice before divine justice.
    Blaise Pascal (1623–1662)

    One encounters very capable fathers abashed by their piano-playing daughters. Three measures of Schumann make them red with embarrassment.
    Alfred Döblin (1878–1957)
