1 4 Ju n 20 01 Palindrome complexity

We study the palindrome complexity of infinite sequences on finite alphabets, i.e., the number of palindromic factors (blocks) of given length occurring in a given sequence. We survey the known results and obtain new results for some sequences, in particular for Rote sequences and for fixed points of primitive morphisms of constant length belonging to “class P” of Hof-Knill-Simon. We also give ...

We discuss the impact of different measurements of the d/u asymmetry in the extraction of parameterizations of parton distribution functions.

An unfactorized and relativistic framework for calculating A(e, e ′ p) observables at typical JLAB energies is presented. Results of (e, e ′ p) model calculations for the target nuclei 12 C and 16 O are presented and compared to data from SLAC and JLAB.
