1-that the chosen works it is devoted to analytical geometry. The book is the first original textbook written in Uzbek in 30 years, added and in a consequence included in the chosen works. The book is written on the basis of 40 years' pedagogical activity of the scientist. The textbook has served not one generation of students. Development of science and culture, growth of requirements to a training material promoted reprinting of the book many years later.

The author states material with such skill that the book can be recommended to any higher educational institution including to the highest technical educational institutions.

2 and 3 volumes are visited to a course of the mathematical analysis. According to the author, "Mathematicians are the cornerstone the simple truth which is repeatedly proved by the life. Thanks to laborious work, the potential of mathematics will grow and develop. Mathematics of today - result of creative activity of many generations of scientists and minds".

The 4th it is based on the doctoral dissertation about the differential equations. Including Bernoulli, Bessel, Boole, Goursat, Clairaut, Cauchy, Lagrange, Legendre, Liouville's equations, Sharpi, Euler and Jacobi are considered. Also in the book ways of the decision above the mentioned equations are stated. In details speaks, the fact that the differential equations are fundamentals of many theoretical technical science.

The 5-volume is devoted to interrelation of culture and science in our republic.

In the book along with mathematics, physics, natural sciences it is about music, cinema, dramatic art and theater.

In Europe Ulugbek's contribution to world science and astronomy is known since the 17th century. His book "Zidzh" (the main book devoted to the astronomical table) is translated into French. It is much also written in Russian. But as the astronomer, the mathematician and the public figure I have written the main book about Ulugbeke Kary-Niyazov. His work "Astronomical School Ulugbeka" has been published in 1950 in Russian in the city of Moscow.
