Irreversible quantum baker map.
We propose a generalization of the model of classical baker map on the torus, in which the images of two parts of the phase space do overlap. This transformation is irreversible and cannot be quantized by means of a unitary Floquet operator. A corresponding quantum system is constructed as a completely positive map acting in the space of density matrices. We investigate spectral properties of t...
متن کاملUnivalent Baker Domains
We classify Baker domains U for entire maps with fj U univalent into three diierent types, giving several criteria which characterize them. Some new examples of such domains are presented, including a domain with disconnected boundary in C and a domain which spirals towards innnity.
متن کاملThe Peano-baker Series
Abstract. This note reviews the Peano-Baker series and its use to solve the general linear system of ODEs. The account is elementary and self-contained, and is meant as a pedagogic introduction to this approach, which is well known but usually treated as a folklore result or as a purely formal tool. Here, a simple convergence result is given, and two examples illustrate that the series can be u...
متن کاملLeaf anatomy and its contribution to the systematics of Aechmea subgenus Macrochordion (de Vriese) Baker (Bromeliaceae).
The leaf anatomy of the species Aechmea subgenus Macrochordion was analyzed to obtain valuable data on their taxonomic delimitation and to identify anatomical adaptations to their respective habitats and habits. All leaves of these species are hypostomatic, and present: peltate trichomes on both surfaces; stomata sunk in epidermal depressions; small epidermal cells with thick walls and inclusio...
متن کاملGeorge Baker: translator of Aparicio de Zubia's pamphlet on the "Oleum Magistrale".
The present article is concerned with identifying the Morisco healer Aparicio de Zubia as the author of a pamphlet on the "Oleum Magistrale" which, in 1566, was published at the instance of the Spanish government after Zubia's death and which, in 1574, was translated by the Elizabethan surgeon George Baker from what seems to have been a French intermediary version. I shall not presume to enter ...
