 On Tychonofftype hypertopologies by Georgi Dimov, Franco Obersnel and Gino Tironi (Site not responding. Last check: 20071019) 
  In 1975, M. Choban introduced a new topology on the set of all closed subsets of a topological space, similar to the Tychonoff topology but weaker than it. 
  In 1998, G. Dimov and D. Vakarelov used a generalized version of this new topology, calling it Tychonofftype topology. 
  Tychonoff topology, Tychonofftype topology, Tspace, commutative space, $\mathcal{O}$commutative space, $\mathcal{M}$cover, $\mathcal{M}$closed family, $P_\infty$space.
