Bochner-khintchine theorem
WebThis theorem of Bochner has extensions in the compact case to projective and conformai vector fields due respectively to Couty [C] and Yano [Yn 1], as well as a refinement due to Frankel [F]; we now discuss these. Couty's theorem states that on a compact Riemannian manifold of negative Ricci curvature, every projective ... Webquote a few examples, the Bochner theorem on semi-definite forms is called the Bochner-Khintchine Theorem (p. 274). The Wiener-Khintchine theorem on stationary processes "lost" any reference to Wiener (p. 371), and on page 378 the Birkhoff-Khintchine ergodic theorem appears. There are also curious changes in the opposite direction. For example …
