The main result of this paper is to establish the weak* completely contractive approximation property (w*CCAP) for the q-Gaussian algebras for all values of q \in [-1, 1] and any number of generators. We use this to establish that the q-Gaussian algebras are strongly solid in the sense of Popa and Ozawa for q \in (-1, 1).

  1. W*-correlations of II$_1$ factors and rigidity of tensor products and graph products

    math.OA 2025-07 conditional novelty 7.0 of 10

    Different subsets F of {2,3,...} give groups G_F whose von Neumann algebras are not W*-correlated, hence not measure equivalent nor W*-equivalent.

  2. Simplicity of q-Gaussian C*-algebras

    math.OA 2026-06 unverdicted novelty 6.0 of 10

    q-Gaussian C*-algebras for |q|<1 are shown to satisfy the Dixmier averaging property and therefore are simple with a unique trace, via rapid decay and spectral gap estimates from free probability.

  3. Curvature, Dolbeault-Dirac operators, and an $\mathrm{L}^p$-index theorem on compact K\"ahler manifolds

    math.FA 2024-01 unverdicted novelty 6.0 of 10

    Proves L^p-index theorem for Dolbeault-Dirac operators on compact Kähler manifolds with index equal to holomorphic Euler characteristic χ(M,E) independent of p, using new abstract curvature bound for semigroups.
