We investigate the representation of a symmetric group Sn on the homology of its Quillen complex at a prime p. For homology groups in small codimension, we derive an explicit formula for this representation in terms of the representations of symmetric groups on homology groups of p-uniform hypergraph matching complexes. We conjecture an explicit formula for the representation of Sn on the top h...

Bu bildiride, açık döngülü piezo-elektrik doğrusal sürücüler için yüksek çözünürlükte histerez telafisi gösterilmektedir. Piezo-elektrik malzemelerde yapıları gereği mevcut olan doğrusalsızlıklar, Bouc-Wen modeli kullanılarak model tabanlı bir kontrol algoritması ile telafi edilmiştir. Telafi için kullanılan yöntemin histerez davranışında zaman, değişen frekans ve farklı hareket genişliği neden...

Abstract The problem of inhibition horseshoe chaos in a nonlinear hysteretic systems using negative stiffness is investigated this paper. Bouc–Wen model used to describe the force produced by both purely and linear elastic springs. analytical investigation Hamiltonian shows that appearance separatrix system directly related parameters forces. This means transverse intersection between perturbed...

The various mathematical models for hysteresis such as Preisach, Krasnosel’skii–Pokrovskii (KP), Prandtl–Ishlinskii (PI), Maxwell-Slip, Bouc–Wen and Duhem are surveyed in terms of their applications in modeling, control and identification of dynamical systems. In the first step, the classical formalisms of the models are presented to the reader, and more broadly, the utilization of the classica...

For any characteristic zero coefficient field, an irreducible representation of a finite p-group can be assigned a Roquette p-group, called the genotype. This has already been done by Bouc and Kronstein in the special cases Q and C. A genetic invariant of an irrep is invariant under group isomorphism, change of coefficient field, Galois conjugation, and under suitable inductions from subquotien...

All the results in this work concern (finite) p-groups. Chapter 1 is concerned with classifications of some classes of p-groups of class 2 and there are no particularly new results in this chapter, which serves more as an introductory chapter. The “geometric” method we use for these classifications differs however from the standard approach, especially for p-groups of class 2 with cyclic center...
