  • On the Levy-Raikov-Marcinkiewicz Theorem 

    Ostrovskii, I.; Ulanovskii, A. (Elsevier, 2003-02-01)
    Let μ be a finite non-negative Borel measure. The classical Lévy-Raikov-Marcinkiewicz theorem states that if its Fourier transform μ̂ can be analytically continued to some complex half-neighborhood of the origin containing ...
  • On the Levy-Raikov-Marcinkiewicz theorem 

    Ostrovskii, I.; Ulanovskii, A. (Elsevier, 2004-08-01)
    Let μ be a finite non-negative Borel measure. The classical Lévy-Raikov-Marcinkiewicz theorem states that if its Fourier transform μ̂ can be analytically continued to some complex half-neighborhood of the origin containing ...
  • Dilations of some VH-spaces operator valued invariant kernels 

    Gheondea, A. (Springer Verlag, 2012)
    We investigate VH-spaces (Vector Hilbert spaces, or Loynes spaces) operator valued Hermitian kernels that are invariant under actions of *-semigroups from the point of view of generation of *-representations, linearizations ...
  • Mackey functions, induction from restriction functors and coinduction from transfer functors 

    Coskun, O. (Elsevier, 2007-09-01)
    Boltje's plus constructions extend two well-known constructions on Mackey functors, the fixed-point functor and the fixed-quotient functor. In this paper, we show that the plus constructions are induction and coinduction ...
  • Bohr Phenomena for Laplace-Beltrami Operators 

    Kaptanoglu, H. T. (Elsevier, 2006-09-25)
    We investigate a Bohr phenomenon on the spaces of solutions of weighted Laplace-Beltrami operators associated with the hyperbolic metric of the unit ball in ℂN. These solutions do not satisfy the usual maximum principle, ...
  • Triplets of Closely Embedded Dirichlet type spaces on the Unit Polydisc 

    Cojuhari, P.; Gheondea, A. (Springer Basel, 2013)
    We propose a general concept of triplet of Hilbert spaces with closed embeddings, instead of continuous ones, and we show how rather general weighted L2 spaces yield this kind of generalized triplets of Hilbert spaces for ...
  • Primary decomposition of the J-groups of complex projective and lens spaces 

    Dibag, I. (Elsevier, 2006-08-01)
    We determine the decomposition of J-groups of complex projective and lens spaces as a direct-sum of cyclic groups. © 2005 Elsevier B.V. All rights reserved.
  • Linear colorings of simplicial complexes and collapsing 

    Civan, Y.; Yalcin, E. (Elsevier, 2007-10)
    A vertex coloring of a simplicial complex Δ is called a linear coloring if it satisfies the property that for every pair of facets (F1, F2) of Δ, there exists no pair of vertices (v1, v2) with the same color such that v1 ...
  • On the infimum for quantum effects 

    Gheondea, A.; Gudder, S.; Jonas, P. (American Institute of Physics, 2005)
    The quantum effects for a physical system can be described by the set E (H) of positive operators on a complex Hilbert space H that are bounded above by the identity operator. While a general effect may be unsharp, the ...
  • Interplay of gouge, fluid pressure and porosity in fault zones 

    Tuncay, K.; Ozkan, G.; Ortoleva, P. (Elsevier, 2003-05)
    The objective of this study is to demonstrate how fault dynamics may naturally be placed in the context of incremental stress theory, rock textural evolution modeling and standard conservation laws. Casting the fault ...
  • A note on the Hilbert ideals of a cyclic group of prime order 

    Sezer, M. (Elsevier, 2007-12-01)
    The Hilbert ideal is the ideal generated by positive degree invariant polynomials of a finite group. For a cyclic group of prime order p, we show that the image of the transfer lie in the ideal generated by invariants of ...
  • Homotopy representations over the orbit category 

    Hambleton, I.; Yalcin, E. (International Press, 2014-11-24)
    Let G be a finite group. The unit sphere in a finite-dimensional orthogonal G-representation motivates the definition of homotopy representations, due to tom Dieck. We introduce an algebraic analogue and establish its basic ...
  • Dual pi-Rickart Modules 

    Ungor, B.; Kurtulmaz, Y.; Halicioglu, S.; Harmanci, A. (, 2012)
    Let R be an arbitrary ring with identity and M a right R-module with S = EndR(M). In this paper we introduce dual -Rickart modules as a generalization of -regular rings as well as that of dual Rickart modules. The module ...
  • Tornehave morphisms, II: The lifted Tornehave morphism and the dual of the Burnside functor 

    Barker, L. (Elsevier, 2010-10)
    We introduce the lifted Tornehave morphism tornπ : K → B*, an inflation Mackey morphism for finite groups, π being a set of primes, K the kernel of linearization, and B* the dual of the Burnside functor. For p-groups, tornp ...
  • Bockstein closed 2-group extensions and cohomology of quadratic maps 

    Pakianathan, J.; Yalcin, E. (Elsevier, 2012-05-01)
    A central extension of the form E: 0 → V→ G→ W→ 0, where V and W are elementary abelian 2-groups, is called Bockstein closed if the components qi∈H *(W,F 2) of the extension class of E generate an ideal which is closed ...
  • Real representation spheres and the real monomial Burnside ring 

    Barker, L.; Tuvay, I. (Elsevier, 2012-03-01)
    We introduce a restriction morphism, called the Boltje morphism, from a given ordinary representation functor to a given monomial Burnside functor. In the case of a sufficiently large fibre group, this is Robert Boltje's ...
  • A Tate cohomology sequence for generalized Burnside rings 

    Coskun, O.; Yalcin, E. (Elsevier, 2009-07)
    We generalize the fundamental theorem for Burnside rings to the mark morphism of plus constructions defined by Boltje. The main observation is the following: If D is a restriction functor for a finite group G, then the ...
  • Continuum quantum systems as limits of discrete quantum systems. I: state vectors 

    Barker, L. (Elsevier, 2001-10-20)
    Dynamical systems on "continuum" Hilbert spaces may be realized as limits of dynamical systems on "discrete" (possibly finite-dimensional) Hilbert spaces. In this first of four papers on the topic, the "continuum" and ...
  • Grobner bases for the Hilbert ideal and coinvariants of the dihedral group D2p 

    Kohls, M.; Sezer, M. (Wiley-VCH Verlag, 2012-11)
    We consider a finite dimensional representation of the dihedral group D2p over a field of characteristic two where p is an odd integer and study the corresponding Hilbert ideal IH. We show that IH has a universal Gr¨obner ...
  • Fusion System and group actions with abelian isotropy subgroups 

    Unlu, O.; Yalcin, E. (Edinburgh Mathematical Society, 2013)
    We prove that if a finite group G acts smoothly on a manifold M such that all the isotropy subgroups are abelian groups with rank ≤ k, then G acts freely and smoothly on M × double struk S signn1 ×... × double struk S ...
