On 3-topological version of \(\Theta\)-regularity
Summary: We modify the concept of \(\theta\)-regularity for spaces with two and three topologies. The new, more general property is fully preserved by sums and products. Using some bitopological reductions of this property, \textit{E. Michael}'s theorem for several variants of bitopological paracompactness is proved [Proc. Am. Math. Soc. 4, 831-838 (1953; Zbl 0052.18701)].
