5 Feb 2018: ables. By writing θa = Nabθ′b for some N GL(2k,R), show that Pfaff(NTAN) =. det(N) Pfaff(A). Show that N may be chosen so as to put A ... b) 〈ψf|eTH|ψi〉, where ψi,f (x) = 〈x|ψi,f〉 are arbitrary states in the Hilbert space.

3 Oct 2018: Some examples of convex sets:. • Halfspaces: {x Rn : 〈a,x〉 b} where a Rn {0} and b R. • ... C. Let a = y pC (y) and b = 〈a,pC (y)〉 12‖a‖.

13 Dec 2018: 6 is implemented if it is of the form 6(a) = ba-ab for all a in A and for some b in B(H). ... PROOF. It is immediate from Corollary 1 and Lemma 6 that if the extension exists, then it is implemented on S2 by some operator b2 in B(H2), where b2 commutes

11 Oct 2018: Thenwe will show that these are the only ones. 2. • Assume A,B Sn+ are such that A B = λxxT for some λ 0. ... Note: Historically, linear programming appeared in 1940s, much earlier than conic programs.Conic programs were introduced in 1990s as a

13 Dec 2018: Unless [A, B] = 0, in which case (5) is exact, some subtlety is needed in characterizing [A, B] as “small.” The natural measure for bounded operators, [[[A, B]11/(211All /B[]), ... 2) lml reaches a maximum at every point on St with respect to some

13 Dec 2018: 8 is implemented if it is of the form 8 ( a ) = b a - a b for all a in A, for some b E B(E). ... London Math. Soc. 43. (1981), 334-356. 4. J. R. Ringrose, On some algebras o[ operators, Proc.

13 Dec 2018: where the superscript denotes an X derivative of some de-gree, and h is any function. ... If we assume that the solution is of order a, then ak- a X(2kAo)a, where X is some constant that will vary withrealizations.

22 Jan 2018: EA(x,t) = cAtn/2 exp(x Bx/4t). and zero elsewhere, for some B Matn(C) and constant cA, both of which will obviously depend on A.For EA to ... Hence. sing supp F {. (t,x) : x p|p|. t = 0 for some p 6= 0}. =
