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:

    ... no one who has not been an integral part of a slaveholding community, can have any idea of its abominations.... even were slavery no curse to its victims, the exercise of arbitrary power works such fearful ruin upon the hearts of slaveholders, that I should feel impelled to labor and pray for its overthrow with my last energies and latest breath.
    Angelina Grimké (1805–1879)

    Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.
    Richard Dawkins (b. 1941)

    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)

    Put shortly, these are the two views, then. One, that man is intrinsically good, spoilt by circumstance; and the other that he is intrinsically limited, but disciplined by order and tradition to something fairly decent. To the one party man’s nature is like a well, to the other like a bucket. The view which regards him like a well, a reservoir full of possibilities, I call the romantic; the one which regards him as a very finite and fixed creature, I call the classical.
    Thomas Ernest Hulme (1883–1917)

    I hear America singing, the varied carols I hear,
    Those of mechanics, each one singing his as it should be blithe and
    strong,
    The carpenter singing his as he measures his plank or beam,
    The mason singing his as he makes ready for work, or leaves off
    work,
    Walt Whitman (1819–1892)
