  • A linear algorithm of checking of the graph connectness 
    Dudchenko, I.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2012)
    An algorithm of sorting of all simply laced graph such that subalgorithm of checking of that the graph is connected is of linear dependence on the number of vertices of the graph.
  • Exponent matrices and topological equivalence of maps 
    Fedorenko, V.; Kirichenko, V.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2007)
    Conjugate classes of continuous maps of the interval [0,1] into itself, whose iterations form a finite group are described. For each of possible groups of iterations one to one correspondence between conjugate classes of ...
  • On indices and eigenvectors of quivers 
    Dudchenko, I.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2019)
    We study formulas for eigenvectors of strongly connected simply laced quivers in terms of eigenvalues. The relation of these formulas to the isomorphism of quivers is investigated.
  • On the dimension of Kirichenko space 
    Plakhotnyk, M. (Algebra and Discrete Mathematics, 2006)
    We introduce a notion of the Kirichenko space which is connected with the notion of Gorenstein matrix (see [2], ch. 14). Every element of Kirichenko space is an n × n matrix, whose elements are solutions of the equations ...
  • Quivers of 3×3 exponent matrices 
    Dokuchaev, M.; Kirichenko, V.V.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2015)
    We show how to use generating exponent matrices to study the quivers of exponent matrices. We also describe the admissible quivers of 3×3 exponent matrices.
  • Quivers of 3×3-exponent matrices 
    Dokuchaev, M.; Kirichenko, V.V.; Plakhotnyk, M. (Algebra and Discrete Mathematics, 2015)
    We show how to use generating exponent matrices to study the quivers of exponent matrices. We also describe the admissible quivers of 3×3 exponent matrices.
