We shall be particularly interested in how general functions can be written as sums of series of simple functions such as power functions and trigonometric functions. This will take us to the theories of power series and Fourier series. 4.1 limsup and liminf In this section we shall take a look at a useful extension of ...

(ii) If A n → A then P(A n) → P(A). For a probability measure µ and a sequence of functions f n (think f n = I A n) (i) is sometimes written with functional notation Z liminf f ndµ ≤ liminf Z f ndµ. A typical use of Fatous lemma is the following. Suppose we have f n ...
Nettetwhere the expressions inside the brackets on the right are, respectively, the limit infimum and limit supremum of the real-valued sequence (). Again, if these two sets are equal, then the set-theoretic limit of the sequence exists and is equal to that common set, and either set as described above can be used to get the limit.; To see the equivalence of the … NettetHere I tried to provide an intuitive explanation of these two limits.#####If you'd like to donate to the success of my channel, please feel free to...
