Dimension of indiscernibility equivalences. (English) Zbl 0629.03034

The authors (students at present) give a new property describing the dimension for compact metrizable spaces. They prove their definition being equivalent with the covering dimension. This is defined in an essentially nonstandard way and is based on the possibility of refining the topology to a totally disconnected one in a certain special manner.
