    Introduction: Understanding how HIV epidemics are likely to behave in the future is key to informing HIV response strategies in low-income countries. Up-to-date HIV epidemiological estimates are important for policy decision- making, but surveillance data can be out of date...

    On the Dunford-Pettis Property of Order p of tensor products

    Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Ioana Ghenciu --- University of Wisconsin-River Falls, USA
    In this paper we give sufficient conditions on Banach spaces X and Y so that the injective tensor product X ⊗ε Y and the dual (X ⊗π Y )∗ of their projective tensor product, do not have the DPPp ,...
  55. Characterizations of the semi-harmonious and harmonious quasi-projection pairs on Hilbert &lt;em&gt;C&lt;/em&gt;
               &lt;sup&gt;&lowast;&lt;/sup&gt;-modules

    Characterizations of the semi-harmonious and harmonious quasi-projection pairs on Hilbert C -modules

    Item type: Journal Article • Journal: Quaestiones Mathematicae • Authors: Xiaoyi Tian --- Shanghai Normal University, P.R. China Qingxiang Xu --- Shanghai Normal University, P.R. China Chunhong Fu --- Health School Attached to Shanghai University of Medicine &amp; Health Sciences, P.R. China
    For each adjointable idempotent Q on a Hilbert C ∗ -module , a specific projection m(Q) called the matched projection of Q was introduced recently due to the characterization of the minimum value among all the distances from projections to Q...
