A function : (0,0) - 0.00) is called a Young function, if 1. w is not identically 0. 2. lm, (u) = (0) = 0, 3. is convex on (0..) and lim, (u) = (b) (convention here poo) = o), where by = supu > 0: p(x) < oo). For a Young function we define = supu > 0: (u) = 0) du = sup{u € 0.6-): v(u/2) = v(u)/2) We also define Op(u) > 0:{u) + (0) = w),...

Please help! Thank you so much!!! 1. A module P over a ring R is said to be projective if given a diagram of R-module homomor phisms with bottom row exact (i.e. g is surjective), there exists an R-module P → A such that the following diagram commutes (ie, g。h homomorphism h: (a) Suppose that P is a projective R-module. Show that every short exact sequence 0 → ABP -0 is split exact (and hence B A P). (b) Prove...
solve problem #1 depending on the given information Consider the following 1D second order elliptic equation with Dirichlet boundary conditions du(x) (c(x)du ) = f(x) (a $15 b), u(a) = ga, u(b) = gb dr: where u(x) is the unknown function, ga and gb are the Dirichlet boundary values, c(x) is a given coefficient function and f(x) is a given source function. See the theorem 10.1 in the textbook for the existence and uniqueness of the solution. 1.1 Weak Formulation...
real analysis 1,3,8,11,12 please 4.4.3 4.4.11a Limits and Continuity 4 Chapter Remark: In the statement of Theorem 4.4.12 we assumed that f was tone and continuous on the interval I. The fact that f is either stric tric. strictly decreasing on / implies that f is one-to-one on t one-to-one and continuous on an interval 1, then as a consequence of the value theorem the function f is strictly monotone on I (Exercise 15). This false if either f is...
(6) (This question does not relate to the above conditions.) Prove that the following system of trigonometric functions is an orthonormal system of L?(-7,7): cos no, sin ne 27 n=1,2,.. Moreover, set f(0) = 62. Write the Fourier expansion off with respect to the system of trigonometric functions in L'(-, 7). Problem 2. We define k00 Example. Let N be a null set. If u(x) = v(x) for x® N, then u(x) = v(x) a.e. Similarly, if lim uk(x) =...
