    A Lichnerowicz vanishing theorem for the maximal Roe algebra

    We show that if a countable discrete group acts properly and isometrically on a spin manifold of bounded Riemannian geometry and uniformly positive scalar curvature, then, under a suitable condition on the gro...

    Multiplier convergent series and uniform convergence of map** series

    In this paper, we introduce the frame property of complex sequence sets and study the uniform convergence of nonlinear map** series in β-dual of spaces consisting of multiplier convergent series.

    Matrix transformations of l q (X) to l p (Y)

    Let X and Y be Banach spaces, 0 < q < +∞, 1 ≤ p < +∞. In this paper, we characterize matrix transformations of l q (X) to l p ...
