Parity-alternating permutations and successions
The study of parity-alternating permutations of {1, 2, . . . , n} is extended to permutations containing a prescribed number of parity successions – adjacent pairs of elements of the same parity. Several enumeration formulae are computed for permutations containing a given number of parity successions, in conjunction with further parity and length restrictions. The objects are classified using ...
متن کاملAlternating traps in Muller and parity games
Muller games are played by two players moving a token along a graph; the winner is determined by the set of vertices that occur infinitely often. The central algorithmic problem is to compute the winning regions for the players. Different classes and representations of Muller games lead to problems of varying computational complexity. One such class are parity games; these are of particular sig...
متن کاملThe shape of the unidentified infra-red bands: analytical fit to ISOCAM spectra
Modelling the unidentified infrared dust bands at 6.2 7.7, 8.6, 11.3, and 12.7 μm by Lorentz profiles is shown to produce excellent fits to the spectra obtained with the Continuous Variable Filter (CVF) of the instrument ISOCAM, on-board the Infrared Space Observatory (ISO). The feature pedestals are accounted for by the wide wings of the Lorentz curves which also account for a large fraction o...
متن کاملParity violation in nuclear systems
Parity violation in nuclear systems is reviewed. A few ingredients relevant to the description of the parity-violating nucleon-nucleon force in terms of meson exchanges are reminded. Effects in nuclear systems are then considered. They involve pp scattering, some complex nuclei and the deuteron system. PACS. 24.80.+y Nuclear tests of fundamental interactions and symmetries
متن کاملCombinatorics in the group of parity alternating permutations
We call a permutation parity alternating, if its entries assume even and odd integers alternately. Parity alternating permutations form a subgroup of the symmetric group. This paper deals with such permutations classified by two permutation statistics; the numbers of ascents and inversions. It turns out that they have a close relationship to signed Eulerian numbers. The approach is based on a s...
