  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
