Dear colleagues,

The National University of Uzbekistan named after Mirzo Ulugbek, the Institute of Mathematics named after V. I. Romanovsky of the Academy of Sciences of the Republic of Uzbekistan, King Abdulaziz university and TAIF university(Saudi Arabia) are holding a international scientific conference “Modern Problems of Applied Mathematics and Information Technologies” in TAIF university(Saudi Arabia), from November 10 to 13, 2025.

Purpose of the conference

This conference aims to study and promote the scientific heritage of the great scholars Musa Al-Khwarazmi to discuss the current status and development prospects of applied mathematics, information technologies, mathematics and its various directions, to attract talented young people to the conference and the main goal of the conference is to establish close scientific relations between the scientists of the countries.

A brief history of the conference

The conference has been held in universities in different regions of the country since the end of the 1990s. The last time it was held was at the beginning of 2024 at the Natinal university of Uzbekistan of the city of Tashkent. In previous years, it was held in cities such as Fergana, Bukhara and Samarkand. These conferences were hosted by Bukhara State University, Samarkand State University, Fergana Polytechnic University and National Universities of Uzbekistan. The conference was held online and offline each time. It was attended by well-known specialists of our country as well as world-renowned scientists.

Abu Abdulloh Muhammad ibn Musa al-Khwarizmi

Muhammad al-Khorazmi is a scientist who made an invaluable contribution to world science with his genius discoveries. Taking into account that he was invited to the palace of Ma'mun ibn Harun al-Rashid, the governor of Khurasan in Baghdad, in the early 800s, he studied in his native Khorezm and became a famous scholar in his twenties. In 813, Mamun took the caliphate crown and moved to Baghdad with the scholars gathered in Marw. A great lover of science, Ma'mun founded "Bayt al-hikma" ("House of Wisdom"), which is called "Baghdad Academy" in the history of science. Muhammad al-Khorazmi was the director of this scientific center until the end of his life. Many scientists from the Arab East and countries of Central Asia worked here. A library full of ancient manuscripts and a specially built observatory served them.

Muhammad al-Khorazmi was the author of more than 20 scientific works, 7 of which have survived to our time. Including:

• "Fi hisab al-Hind" (Arabic "Book on Indian calculation") is a work representing the decimal positional counting system and describing nine numbers with a zero sign.

• "Al-kitab al-mukhtasar fi hisab al-jabr wa al-muqabala". (A short book on Al-Jabr and Al-Muqabala calculus, written in Arabic) - a book called "Algebra" by the author, considering algebra as a science.

• Ziji al-Khwarazmi (written in Arabic ("Zij") "Astronomical table") is a work consisting of a small theoretical section and tables containing the trigonometric functions of sines.

• "Kitab surat al-arz" (written in Arabic "The book of the picture of the Earth") is a geographical treatise containing a map of the eastern half of the planet Earth, the countries on it, the Pacific Ocean (Bahr al-muzallam) and the map of our planet for the first time in the Middle Ages.

Muhammad al-Khorazmi's important contribution to the sciences of mathematics, astronomy and geography, and through them to the development of civilization:

1. He founded the number system representing nine digits with a zero sign, which represents the decimal positional calculation.

2. He created algebra as a science and gave it that name.

3. He developed a new method of scientific and educational works through clear and understandable rules, called "Algorithm" in European literature, and launched them. In Latin, the pronunciation of "algorithm" is equivalent to his name - al-Khwarizmi. This concept of algorithm forms the basis of all modern digital information and computer technologies. It is through this method that the description of Muhammad al-Khwarazmi's works has spread to the general public. In addition to the aforementioned services, it is now known that he used pole points.

4. The Astronomical book of Muhammad al-Khorazmi ("Ziji") deals with the Sun, the Moon, the five planets, mathematical geography, trigonometry, and eclipses of the Sun and the Moon. The book was translated into Latin in 1126, German in 1914, and English in 1962.

5. Muhammad al-Khorazmi's geographical works describe the known places on earth at that time. In the work, the places are presented with a clear map, the rivers, seas and oceans there, and a significant population of 2402. It was the first geographical work in Arabic written in the Middle Ages. This climate theory played an important role in the development of geography.

Muhammad al-Khwarizmi's contribution to the development of mathematics and civilization, in general, is recognized, his name is stamped on "algorithm" and the term "algorithm" in one of his works is proof of his uniqueness among Eastern scientists. "The greatest mathematician of his time, by all accounts one of the greatest scientists of all time" was given by the American historian Dj.Sarton
