Debates a decade ago with Mark Barkan, Josť M. Vicente Gomila, and Iouri Belski

Recently while browsing through the old mail I came across the discussions with the afore mentioned gentlemen happened before this journal came into being. The discussions are instructive and fall into the scope of the journal. That is why I decided to devote this issue to their publication.

I hope the readers will enjoy them and will send in their comments.
