Many thanks for the opportunity to give a talk at your remarkable congress. I was somewhat skeptical about the event at the initial stage of preparation, but my opinion changed when I received the program. The breadth of your geographical coverage made an impression. I will not make a detailed analysis of the reports, but would like to note that some of the talks I listened to made the strongest positive impression both in the depth of the material and in the originality of the presentation form. Of course, with such coverage, technical failures are inevitable, but you have successfully overcome them. I am sincerely grateful for the opportunity to participate. I wish you success in your future work.
