Dear Professor Grushka, Do you intend to write something about the theory of changeable sets for non-expert readers? I think that his works on the subject are very interesting in many respects, but usually too technical perhaps for non-mathematicians or mathematicians working in a different field. Since this theory has applications in both physics and mathematics, I believe such an introduction would be very interesting! With my best Regards, Ricardo Vieira.
1) I would like to clarify the question. Did You mean the theory of CHANGEABLE sets?
2) Concerning the theory of changeable sets, first of all, I plan to implement my minimum program of obtaining new interesting results. And then I might begin deal with their popularization. At the present time, the most complete and understandable exposition of this theory You can find in the preprint "Draft Introduction to Abstract Kinematics. (Version 2.0)" (https://doi.org/10.13140/RG.2.2.28964.27521 or http://vixra.org/pdf/1701.0523v2.pdf). Also I plan to rewrite more popularly the introductory sections of this preprint in it's future third version to do more understandable the motivation of fundamental definitions of changeable set theory.
3) I am very grateful for your comment and positive general assessment for perspectives of my activity, and I will bear in mind your suitable remark about popularization of the results.
With best regards Yaroslav Grushka.
Dear Prof. Grushka,
Sorry for confusion about the words "interchangeable" and "changeable", and thank you for send your preprint. Best regards. Ricardo.
