  • Latin quandles and applications to cryptography 

    Isere, Abednego Orobosa; Adéníran, John Olúsolá; Jaiyéolá, Temitópé Gbóláhán (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    This work investigated some properties of Latin quandles that are ap-plicable in cryptography. Four distinct cores of an Osborn loop (non-diassociativeand non-power associative) were introduced and investigated. The necessary ...
  • Duality of conservation laws and their role in the processes of emergence of physical structures and formations 

    Petrova, Ludmila I. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    As it is known, the conservation laws for material media are conservationlaws for energy, linear momentum, angular momentum, and mass. Such conser-vation laws are described by differential equations. And the conservation ...
  • Bifurcation of positive periodic solutions to non-autonomous undamped Duffing equations 

    Šremr, Jiří (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    We study a bifurcation of positive solutions to the parameter-dependentperiodic problem u′′=p(t)u−h(t)|u|λsgnu+μf(t);u(0) =u(ω), u′(0) =u′(ω),whereλ >1,p,h,f∈L([0,ω]), andμ∈Ris a parameter. Both the coefficientpand the ...
  • An incremental method for the construction of the box extents of a context 

    Radeleczki, Sándor; Veres, Laura (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    In this paper we are improving a method proposed in [2] for the construc-tion of the box extents of a given formal context. We prove that the lattice of thebox extents can be order-embedded in the lattice generated by the ...
  • Sheffer operations in complemented posets 

    Chajda, Ivan; Kolařík, Miroslav (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    We show that in every downward directed poset with an antitone involu-tion the so-called Sheffer operation can be introduced satisfying certain identities.However, also conversely, if we have given a Sheffer operation|on ...
  • The manager sack race game 

    Haugen, Kjetil K. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    This article applies game theory to explain why football clubs have a ten-dency to sack their managers when relegation is a realistic option. As opposedto coach succession literature, which typically ...
  • h-stability and boundedness results for solutions to certain nonlinear perturbed systems 

    Damak, Hanen; Hammani, Mohamed Ali; Kicha, Abir (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2021)
    In this work, we establish some new sufficient conditions to show the uni-formh-stability for nonlinear time-varying perturbed systems which can be viewedas an extension of the uniform exponential stability and polynomial ...
  • In-game betting and the Kelly criterion 

    Andersen, Robin; Hassel, Vegard; Hvattum, Lars Magnus; Stalhane, Magnus (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    When a bet with a positive expected return is available, the Kelly crite-rion can be used to determine the fraction of wealth to wager so as to maximizethe expected logarithmic return on investment. Several variants of the ...
  • Coefficient estimates for special subclasses of k-fold symmetric bi-univalent functions 

    Atshan, Waggas Galib; Yalçın, Sibel; Hadi, Rasha Abbas (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    In the present paper, we consider two new subclasses Nk (μ,) and Nk (μ,) of k consisting of analytic and k-fold symmetric bi-univalent functions defined in the open unit disc U = {z : z 2 C and |z| < 1}. For functions ...
  • On bornological induced pseudonearness 

    Leseberg, Dieter; Vaziry, Zohreh (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    Pseudonearness is considered a common tool for studying bornology,b-topology, pseudoproximity, and last but not least,classicalnearness. For anypseudonear space we construct ab-completion, which generalizes the classical ...
  • On increasing solutions of half-linear delay differential equations 

    Matucci, Serena; Řehák, Pavel (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    We establish conditions guaranteeing that all eventually positive increas-ing solutions of a half-linear delay differential equation are regularly varying andderive precise asymptotic formulae for them. The results presented ...
  • Note on a class of k-paranormal weighted composition operators on the Fock space Fp(C) 

    Santhoshkumar, C.; Veluchamy, T. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    In this paper, we characterize the k-paranormal, isometric, spectral radius and the numerical radius of the weighted composition operator C.
  • Huffman coding and chains in partition lattices 

    Foldes, Stephan (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    The Huffman coding algorithm is interpreted in the context of the lat-tice of partitions of the source alphabet. Maximal chains in the partition latticecorrespond to linear extensions of tree orders, and those among the ...
  • Cycle Systems 

    Pfaltz, John P. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    In this paper we show that the composition (symmetric difference) ofcycles is well-defined. So, such a collection {. . . , Ci, Ck, . . .} of cycles with a com-position operator,◦, is a matroid. As such, it has sets of ...
  • Who are the real top scorers: Algorithmically resorting a top scorer list by a limited set of preference assumptions 

    Hauge, Kjetil K. (Vysoké učení technické v Brně, Fakulta strojního inženýrství, Ústav matematiky, 2020)
    This article presents an algorithm, which by taking both goals scoredas well as matches played into account, is meant to provide “more sensible” topscorer lists in football. The algorithm computes Upper Hulls recursively ...
