Dear Sagdy Khasanovich!

On my return home I would cordially thank you once more for your interest and attention to the
symposium. Your personal participation has heightened the prestige of this scientific forum and – I
hope – was also of interest to you also.

I personally want to thank you for your hospitality extended to me in Tashkent. I am sending you
my last book by way of “scientific exchange” and in memory of recommencement of our
acquaintance. I am also sending you as the chairman of the organizing committee the copies of
gratitude letters for information.

Wishing you good health and new progress,

Yours A. Ershov
