  • Malicki, Piotr (Springer, 2015)
    We determine the Krull dimension of the module category of finite dimensional tame generalized multicoil algebras over an algebraically closed field, which are domestic.
  • Malicki, Piotr; Pena, Jose Antonio; Skowroński, Andrzej (2013-11-25)
    We solve a long standing open problem concerning the structure of finite cycles in the category $\mo A$ of finitely generated modules over an arbitrary artin algebra $A$, that is, the chains of homomorphisms $M_0 \buildrel ...
  • Piersa, Jarosław; Zając, Katarzyna (Springer Berlin Heidelberg, 2013-06-09)
    In this work we provide a spectral comparison of functional networks in fMRI data of brain activity and artificial energy-based neural model. The spectra (set of eigenvalues of the graph adjacency matrix) of both networks ...
  • Piersa, Jarosław; Schreiber, Tomasz (Springer Berlin Heidelberg, 2012-04-29)
    In this work we study a simplified model of a neural activity flow in networks, whose connectivity is based on geometrical embedding, rather than being lattices or fully connected graphs. We present numerical results showing ...
  • Piersa, Jarosław (Springer Berlin Heidelberg, 2012)
    Average path length is recognised as one of the vital characteristics of random graphs and complex networks. Despite a rather sparse structure, some cases were reported to have a relatively short lengths between every pair ...
