  • Higher-dimensional general Jacobi identities I 

    Nishimura, H. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    It was shown by the author [International Journal of Theoretical Physics 36 (1997), 1099{1131] that what is called the general Jacobi identity, obtaining in microcubes, underlies the Jacobi identity of vector elds. It is ...

  • Classification trees in a box extent lattice 

    Veres, L. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    In this paper we show that, during an elementary extension of a context, each of the classi cation trees of the newly created box extent lattice can be obtained by modifying the classi cation trees of the box extent lattice ...

  • On an equation related to nonadditive entropies in information theory 

    Nath, P.; Singh, D. K. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    The paper provides the general solutions of a sum form functional equa- tion containing three unknown mappings with some of the solutions related to the nonadditive entropies in information theory

  • A note on some generalized closure and interior operators in a topological space 

    Gupta, A.; Sarma, R. D. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    If X is a topological space and A X, then the number of distinct sets that can be obtained from A by using all possible compositions for operators i , c (where = ; ; ; ) introduced by Cs asz ar is at the most 25. ...

  • F-resolvable spaces 

    Dahane, I.; Dridi, L.; Lazaar, S. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    In this paper we study topological spaces whose F-re ections are resolv- able. In particular, the re ectors T0, S, , and FH-re ection are characterized.

  • Professor Ladislav Skula is eighty 

    Kureš, M.; Šlapal, J. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    30 June 1937 is the birthday of Professor Ladislav Skula, our colleague at the Institute of Mathematics of the BUT Faculty of Mechanical Engineering, a distinguished editorial board member of this journal, and an outstanding ...

  • Classification of orthogroups as semilattices of various rectangular groups fulfilling x^(p+1)≈x 

    Jende, A. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2017)
    Completely regular semigroups whose idempotents form a subsemigroup are called orthodox completely regular semigroups, or brie y orthogroups. In this paper, we characterize orthogroups which are semilattices of various ...
