Here again is the reference to Schwartz's book, where he defines the minimal dominant set (GeTChA set) along with the union of minimal undominated sets (GOChA set), and a few others.
I reply:
The Smith set certainly has lots of names. It´s the Smith set, the minimal dominant set, and now the GeTCha set too.
As for the GOCha set the uniion of minimal undominated sets, is that what is usually called the Schwartz set?
Ok, so when you say "minimal dominant set" or "GeTCha set", you´re referring to the Smith set, and when you say "GOCha set", you´re referring to the Schwartz set, right?
Didn´t you say that Schwartz´s book or article defining the GeTCha set was written in ´86? But from Markus´s posting, Smith wrote about it in ´73, which seem to justify calling it the Smith set.
Two sets and lots of names.
