• Abstract:
  Theorem: The topological partition relation \omega^{*}\rightarrow(Y)^{1}_{2}

  (a) fails for every space Y with |Y|\geq 2^{\rm \bf c};

  (b) holds for Y discrete if and only if |Y|\leq c;

  (c) holds for certain non-discrete P-spaces Y;

  (d) fails for Y=\omega\cup\{p\} with p\in\omega^{*};

  (e) fails for Y infinite and countably compact.
