Egorov's theorem proof

WebNow we can state the main theorem which tells us that the time-evolution of a semiclassical pseudodi erential operator baW is again a semiclassical pseudodi eren-tial operator whose symbol, to the leading order, is the time-evolution of a: Theorem 2.2 (Egorov’s theorem).

A2: the problem comes from the dependence of the set A and ε. Things are more concrete when we think about X = [0, 1] and fn(x) = xn. 5,793.
