Those notes shape the contents of a Nachdiplomvorlesung given on the Forschungs institut fur Mathematik of the Eidgenossische Technische Hochschule, Zurich from November, 1984 to February, 1985. Prof. okay. Chandrasekharan and Prof. Jurgen Moser have inspired me to write down them up for inclusion within the sequence, released through Birkhiiuser, of notes of those classes on the ETH.

This article is a self-contained and unified therapy of matrix differential calculus, in particular written for econometricians and statisticians. it will probably function a textbook for complicated undergraduates and postgraduates in econometrics and as a reference e-book for working towards econometricians.

This ebook is likely one of the relevant efforts of Turan, an exposition of his energy sum conception. This concept, referred to as "Turan's method," arose as he tried to turn out the Riemann speculation. yet Turan chanced on purposes past these to major numbers. This ebook indicates the efficacy of the facility sum technique and features a variety of functions in its moment half.

Let us show that in such a case the present method does not work. From (6), uϭ Ύ M dx ϩ k(y) ϭ Ϫxy ϩ k(y), hence dk 0u ϭ Ϫx ϩ . 0y dy Now, 0u> 0y should equal N ϭ x, by (4b). However, this is impossible because k(y) can depend only on y. Try (6*); it will also fail. Solve the equation by another method that we have discussed. Reduction to Exact Form. Integrating Factors The ODE in Example 3 is Ϫy dx ϩ x dy ϭ 0. It is not exact. ], (11) Ϫy dx ϩ x dy x 2 ϭϪ y x 2 dx ϩ y 1 dy ϭ d a b ϭ 0. x x Integration of (11) then gives the general solution y>x ϭ c ϭ const.

Such a function F(x, y) is then called an integrating factor of (12). EXAMPLE 4 Integrating Factor The integrating factor in (11) is F ϭ 1>x 2. Hence in this case the exact equation (13) is FP dx ϩ FQ dy ϭ Ϫy dx ϩ x dy x 2 y ϭ d a b ϭ 0. x Solution y x ϭ c. These are straight lines y ϭ cx through the origin. ) It is remarkable that we can readily find other integrating factors for the equation Ϫy dx ϩ x dy ϭ 0, namely, 1>y 2, 1>(xy), and 1>(x 2 ϩ y 2), because (14) Ϫy dx ϩ x dy y 2 x ϭ d a b, y Ϫy dx ϩ x dy xy x ϭ Ϫd aln b , y Ϫy dx ϩ x dy x ϩy 2 2 y ϭ d aarctan b .

We can find this factor F(x) by Theorem 1 in the previous section or we can proceed directly, as follows. We multiply (1) by F(x), obtaining (1*) Fy r ϩ pFy ϭ rF. The left side is the derivative (Fy) r ϭ F r y ϩ Fy r of the product Fy if pFy ϭ F r y, pF ϭ F r . thus By separating variables, dF>F ϭ p dx. By integration, writing h ϭ ͐ p dx, ln ƒ F ƒ ϭ h ϭ Ύ p dx, F ϭ eh. thus With this F and h r ϭ p, Eq. (1*) becomes ehy r ϩ h r ehy ϭ ehy r ϩ (eh) r y ϭ (ehy) r ϭ reh. By integration, ehy ϭ Ύ e r dx ϩ c.
