Indicator Function/characteristic Function in Recursion Theory G%c3%b6dels and Kleenes Representing Function

Famous quotes containing the words function, theory and/or representing:

    “Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
    —Frank Smith (b. 1928)

    “The theory of truth is a series of truisms.”
    —J.L. (John Langshaw)

    “Brave people may be persuaded to an action by representing it as being more dangerous than it really is.”
    —Friedrich Nietzsche (1844–1900)
