Remarks on Form Factor Bounds
Improved model independent upper bounds on the weak transition form factors are derived using inclusive sum rules. Comparison of the new bounds with the old ones is made for the form factors hA1 and hV in B → D decays. [email protected] 1 A set of model independent bounds has been derived to provide a restriction on the shape of weak transition form factors [1–3]. They have been extensive...

متن کاملRemarks on Bounds for Quantum codes
We present some results that show that bounds from classical coding theory still work in many cases of quantum coding theory. 1 Nondegenerate Quantum Codes Let Q be an ((n,K, d)) nondegenerate quantum code with projection operator P . Let Ai and Bi be the quantum enumerators of Q, [1],[2] Ai = ∑ wt(E)=i Tr(EP )Tr(EP ), Bi = ∑ wt(E)=i Tr(EPEP ), where E is an error operator. (See [1],[2] for def...
متن کاملSome remarks on the Brunovsky canonical form
Among the various canonical forms which were proposed for constant linear systems, the one due to Brunovsky [1] certainly is the most profound. It characterizes a dynamics modulo the group of static state feedbacks by a finite set of pure integrators. Its proof, which is quite computational, has been improved in various ways, and can be found in several textbooks (see, e.g., [12, 13, 20, 21] an...
متن کاملSome Remarks on Factor Graphs
The paper is a collection of remarks, some rather plain, on various issues with factor graphs. In particular, it is pointed out that powerful signal processing techniques such as gradient methods, Kalman filtering, and the particle filter can be used and combined in factor graphs.
