Graph Theoretical Analysis of local ultraluminous infrared galaxies and quasars
Orestis Pavlou, Ioannis Michos, Vicky Papadopoulou Lesta +3
We present a methodological framework for studying galaxy evolution by utilizing Graph Theory and network analysis tools. We study the evolutionary processes of local ultraluminous…
Classification of local ultraluminous infrared galaxies and quasars with kernel principal component analysis
Evangelos S. Papaefthymiou, Ioannis Michos, Orestis Pavlou +2
We present a new diagnostic diagram for local ultraluminous infrared galaxies (ULIRGs) and quasars, analysing particularly the Spitzer Space Telescope's Infrared Spectrograph (IRS)…
Enumeration of super-strong Wilf equivalence classes of permutations in the generalized factor order
Ioannis Michos, Christina Savvidou
Super-strong Wilf equivalence classes of the symmetric group on letters, with respect to the generalized factor order, were shown by Hadjiloucas, Michos and Sa…
On super-strong Wilf equivalence classes of permutations
Demetris Hadjiloucas, Ioannis Michos, Christina Savvidou
Super-strong (elsewhere referred to as strong) Wilf equivalence is a type of Wilf equivalence on words that was introduced by Kitaev et al. in 2009. We provide a necessary and suff…
On twin and anti-twin words in the support of the free Lie algebra
Ioannis C. Michos
Let be the free Lie algebra on a finite alphabet over a commutative ring with unity. For a word in the free monoid let denote its reversa…
On the support of the free Lie algebra: the Schützenberger problems
Ioannis Michos
M.-P. Schützenberger asked to determine the support of the free Lie algebra on a finite alphabet over the ring of integers…
