## A remark on $$\Theta$$-regular spaces.(English)Zbl 0888.54027

Summary: An embedding characterization of $$\theta$$-regularity using the Wallman-type compactification is given. The productivity of $$\theta$$-regularity and a slight generalization of Nagami’s product theorem to non-Hausdorff paracompact $$\Sigma$$-spaces are obtained as a corollary.
