  text: "This paper is a continuation of Part I of this project, where we developed
    a new local well-posedness theory for nonlinear stochastic PDEs with Gaussian
    noise. In the current Part II we consider blow-up criteria and regularization
    phenomena. As in Part I we can allow nonlinearities with polynomial growth and
    rough initial values from critical spaces. In the first main result we obtain
    several new blow-up criteria for quasi- and semilinear stochastic evolution equations.
    In particular, for semilinear equations we obtain a Serrin type blow-up criterium,
    which extends a recent result of Prüss–Simonett–Wilke (J Differ Equ 264(3):2028–2074,
    2018) to the stochastic setting. Blow-up criteria can be used to prove global
    well-posedness for SPDEs. As in Part I, maximal regularity techniques and weights
    in time play a central role in the proofs. Our second contribution is a new method
    to bootstrap Sobolev and Hölder regularity in time and space, which does not require
    smoothness of the initial data. The blow-up criteria are at the basis of these
    new methods. Moreover, in applications the bootstrap results can be combined with
    our blow-up criteria, to obtain efficient ways to prove global existence. This
    gives new results even in classical \U0001D43F2-settings, which we illustrate
    for a concrete SPDE. In future works in preparation we apply the results of the
    current paper to obtain global well-posedness results and regularity for several
    concrete SPDEs. These include stochastic Navier–Stokes equations, reaction– diffusion
    equations and the Allen–Cahn equation. Our setting allows to put these SPDEs into
    a more flexible framework, where less restrictions on the nonlinearities are needed,
    and we are able to treat rough initial values from critical spaces. Moreover,
    we will obtain higher-order regularity results."

  text: In the class of strictly convex smooth boundaries each of which has no strip
    around its boundary foliated by invariant curves, we prove that the Taylor coefficients
    of the “normalized” Mather’s β-function are invariant under C∞-conjugacies. In
    contrast, we prove that any two elliptic billiard maps are C0-conjugate near their
    respective boundaries, and C∞-conjugate, near the boundary and away from a line
    passing through the center of the underlying ellipse. We also prove that, if the
    billiard maps corresponding to two ellipses are topologically conjugate, then
    the two ellipses are similar.

  text: We derive optimal-order homogenization rates for random nonlinear elliptic
    PDEs with monotone nonlinearity in the uniformly elliptic case. More precisely,
    for a random monotone operator on \mathbb {R}^d with stationary law (that is spatially
    homogeneous statistics) and fast decay of correlations on scales larger than the
    microscale \varepsilon >0, we establish homogenization error estimates of the
    order \varepsilon in case d\geqq 3, and of the order \varepsilon |\log \varepsilon
    |^{1/2} in case d=2. Previous results in nonlinear stochastic homogenization have
    been limited to a small algebraic rate of convergence \varepsilon ^\delta . We
    also establish error estimates for the approximation of the homogenized operator
    by the method of representative volumes of the order (L/\varepsilon )^{-d/2} for
    a representative volume of size L. Our results also hold in the case of systems
    for which a (small-scale) C^{1,\alpha } regularity theory is available.

  text: We study generic unfoldings of homoclinic tangencies of two-dimensional area-preserving
    diffeomorphisms (conservative New house phenomena) and show that they give rise
    to invariant hyperbolic sets of arbitrarily large Hausdorff dimension. As applications,
    we discuss the size of the stochastic layer of a standard map and the Hausdorff
    dimension of invariant hyperbolic sets for certain restricted three-body problems.
    We avoid involved technical details and only concentrate on the ideas of the proof
    of the presented results.
