Enumeration of Special Sets of Polynomials over Finite Fields

Astrid Reifegerste
1999 Finite Fields and Their Applications  
Our focus is on the enumeration of these special sets of polynomials, in particular, we give the number of squarefree palindromes.  ...  These investigations make it possible to estimate the efficiency of the prefactorization of polynomials over finite fields based on such gcd calculations.

Generating large Ising models with Markov structure via simple linear relations [article]

Nanny Wermuth, Giovanni M. Marchetti
2017 arXiv   pre-print
This implies that the strength of dependences can be assessed locally. We use the results to find a well-fitting general Ising model with hollow-tree structure for a set of longitudinal data.  ...  These structures are especially attractive for palindromic Ising models, which mimic a symmetry of joint Gaussian distributions.  ...  Weck for letting us reanalyze his data and David Cox for most helpful discussions and comments, especially for the proof of equivalence of the model formulations in terms of the log-linear and the hypetan  ...

Wave delocalization and transfer efficiency enhancement in locally symmetric disordered chains [article]

C. V. Morfonios, M. Röntgen, F. K. Diakonos, P. Schmelcher
2018 arXiv   pre-print
The transfer may further be drastically amplified in the presence of spatial overlap between the symmetry domains, and in particular when global and local symmetry coexist.  ...  We find that a transition to more delocalized and fragmented eigenstates occurs for intermediate average symmetry domain sizes, depending on the degree of disorder.  ...  In particular, the possibility to amplify signal transfer by the coexistence of global and local symmetry in composite systems is thus demonstrated.  ...

Pruned Bit-Reversal Permutations: Mathematical Characterization, Fast Algorithms and Architectures [article]

Mohammad M. Mansour
2014 arXiv   pre-print
Serial pruning is a simple technique to alter the length of a permutation to support a wider range of lengths, but results in a serial processing bottleneck.  ...  Using this statistic, a recursive algorithm that computes the minimum inliers count of a pruned BR interleaver (PBRI) in logarithmic time complexity is presented.  ...  To interleave a block of size β, a mother interleaver whose size is the smallest power-of-2 that is ≥ β is selected and pruned. Hence, in the following, we assume that k/2 < β < k.  ...
