Webso-called pointwise trap.) However, this seems highly unlikely, and to that end it is not hard to dispense of. Suppose that f(a) = +a and f(b) = b for now. Exercise 2.3. Plug these into … WebMathematics Home :: math.ucdavis.edu
http://publications.azimpremjifoundation.org/3151/ WebIn mathematics, the qualifier pointwise is used to indicate that a certain property is defined by considering each value of some function An important class of pointwise concepts are the pointwise operations, that is, operations defined on functions by applying the operations to function values separately for each point in the domain of definition.

So really there only is a distinction between pointwise and uniform convergence.
Web5. Beware the \pointwise trap"; for example, you may prove that f(x)2 = x2, hence f(x) = x. This is only necessarily true pointwise! To conclude that the only solutions are f(x) = x for all x and f(x) = x for all x, you will need to use other equations again (otherwise we could
Web§4 Pointwise Trap Pointwise traps usually arise when you think you are done solving a problem. If you’ve proved that f ( x ) = A( x ) or f ( x ) = B( x ) for every point x, you haven’t actually shown that f ≡ A or f ≡ B!
