  1. Foreign direct investment flows and domestic investment in China: A multivariate time series analysis

    Foreign direct investment flows and domestic investment in China: A multivariate time series analysis

    Item type: Journal Article • Journal: Investment Analysts Journal
    This paper explores the effects of inward and outward foreign direct investment (FDI) on domestic investment in China using annual time series data over the period of 1982–2016. The empirical analysis is performed using ARDL bound testing procedure and fully...
  2. 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).
  3. 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...
  4. 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...
  5. 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...
  6. 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...
  7. A note on generating functions for Rogers-Szegő polynomials

    A note on generating functions for Rogers-Szegő polynomials

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In this paper, the details of certain Carlitz's generating functions for Rogers-Szegőpolynomials and their generalizations are given by Carlitz's q-operators. In addition, an additional proof of Srivastava-Jain's generating function is shown. At last, generalizations of Srivastava-Agarwal type generating functions are...
  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...
