The Code Cosycosy Infinity
نویسندگان
چکیده
An overview over the features of version 7 of the code COSY INFINITY is given. Currently distributed to about 160 registered users, the code allows the computation and manipulation of maps of arbitrary order for arbitrary arrangements of elds. Besides the conventional analysis tools including various techniques for symplectic tracking, normal form methods, hardware and reconstructive aberration correction, and achromat design, several new features are presented. These include eecient methods to treat fringe eld, a variety of methods to directly use measured eld data for the computation of maps, as well as the computation and analysis of spin dynamics. Furthermore, we give references regarding the practical use of the new remainder diierential algebraic methods, which among other things allow fully rigorous estimates of stability times of nonlinear repetitive motion.

Evaluation Codes Defined by Plane Valuations at Infinity C. Galindo and F. Monserrat
We introduce the concept of δ-sequence. A δ-sequence ∆ generates a wellordered semigroup S in Z or R. We show how to construct (and compute parameters) for the dual code of any evaluation code associated with a weight function defined by ∆ from the polynomial ring in two indeterminates to a semigroup S as above. We prove that this is a simple procedure which can be understood by considering a p...
متن کاملQuantum Codes on Hurwitz Surfaces
Ever since the birth of the first quantum error correcting code, many error correcting techniques and formalism has been constructed so far. Among those, generating a quantum code on a locally planar geometry have lead to some interesting classes of codes. Main idea of this thesis stems from Kitaev's Toric code, which was the first surface code, yet it suffered from having a asymptotically vani...
