    Some inequalities for <em>L<sub>p</sub></em> radial Blaschke-Minkowski homomorphisms<xref ref-type="fn" rid="FN0001"/>

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    The notion of radial Blaschke-Minkowski homomorphisms was presented by Schuster. Afterwards, Wang et al. introduced Lp radial Blaschke-Minkowski homomorphisms. In this paper, associated with Lp-dual affine surface areas, we establish some inequalities including the Brunn-Minkowski type inequality, cyclic inequality and...

    Some inequalities for asymmetric <em>L<sub>p</sub></em>-mean zonoids<xref ref-type="fn" rid="FN0000"/>

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Based on the notion of Lp-mean zonoids which is introduced by Xi, Guo and Leng, we define the notion of asymmetric Lp-mean zonoids and establish its an affine inequality. Further, we give the extremal values for volume, quermassintegrals of this...
  3. Some determinants of Pascal-like matrices

    Some determinants of Pascal-like matrices

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    By combining the extended Cauchy double alternant with a recent theorem due to Chu (2009), we review some determinantal evaluations for Pascal-like matrices due to Krattenthaler (2002).
  4. ON ESSENTIAL STRONG-NILPOTENCY OF γ-RINGS

    ON ESSENTIAL STRONG-NILPOTENCY OF γ-RINGS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    An ideal I of a Γ-ring M is essential strongly-nilpotent if I contains a strongly-nilpotent ideal N of M such that K ∩ N ≠ 0 whenever K is a non-zero ideal of M contained in I. Let M be...
  5. HOMOLOGICAL DIMENSIONS OF INVARIANTS FOR HOPF ALGEBRA ACTIONS

    HOMOLOGICAL DIMENSIONS OF INVARIANTS FOR HOPF ALGEBRA ACTIONS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Let H be a Hopf algebra acting on a ring A, and let A H denote the invariant subring of A. It is shown that if H is semisimple and A is a finitely generated projective right A H—module then...
  6. On the extension problem between separable smooth Banach spaces with RNP

    On the extension problem between separable smooth Banach spaces with RNP

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we study the extension of isometric operators between unit spheres of separable smooth Banach spaces with the Radon-Nikodym property (RNP). We show that if there is a surjective isometric operator between unit spheres of separable smooth Banach...
  7. On algorithmic aspects of the <em>l</em>-torsion of Brauer groups

    On algorithmic aspects of the <em>l</em>-torsion of Brauer groups

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    We study the algorithmic aspects of the l-torsion of the Brauer group Br(K) of a field K which contains the l-th roots of unity µ l, only provided with basic operations on the elements of K. We use a primitive...
  8. On the isometric extension problem

    On the isometric extension problem

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, we study the isometric extension problem between l ∞ (Γ, E) and l ∞ (▵, E), where E is a real uniformly convex Banach space. We obtain that if Γ > 1, then any surjective...
  9. On harmonic starlike functions with respect to symmetric, conjugate and symmetric conjugate points

    On harmonic starlike functions with respect to symmetric, conjugate and symmetric conjugate points

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In the present paper, we introduce the notions of functions harmonic starlike with respect to symmetric, conjugate and symmetric conjugate points. Such results as coefficient inequalities and structural formulae for these function classes are proved.
  10. Effect of health education on oral hygiene and gingival status of persons living with HIV attending comprehensive care centres in Nairobi, Kenya

    Effect of health education on oral hygiene and gingival status of persons living with HIV attending comprehensive care centres in Nairobi, Kenya

    Item type: Journal Article • Journal: African Journal of AIDS Research
    The study aimed to describe the effect of an oral health education intervention on oral hygiene status and gingival inflammation among persons with HIV attending two comprehensive healthcare centres in Nairobi, Kenya. This was a quasi-experimental study of 195 participants...
