Традиционно Всесибирский конгресс женщин - математиков посвященный дню рождения Софьи Ковалевской проходит в Красноярске в январе один раз в два года на трёх научных площадках: Института Вычислительного моделирования СО РАН, Сибирского федерального университета, Сибирского технологического университета. Четырнадцать лет назад - 15 января 2000 года 150-летие со дня рождения выдающегося русского математика было торжественно отмечено лишь в двух городах мира – Красноярске и Стокгольме. Тогда научный мир Красноярска собрал ученых из Сибири, Дальнего Востока, Урала и Москвы. В это же время состоялось специальное заседание Шведской королевской Академии наук, с которой была тесно связана жизнь и научная деятельность С. Ковалевской. Поэтому от имени Конгресса было послано приветственное поздравление Стокгольмскому университету. И в разгар работы Конгресса получен ответ, в котором сообщалось, что 15 января в присутствии академика РАН О. А. Ладыженской, Российского посла А. Л. Никифорова и ректора Стокгольмского университета К. Линденкрона состоялось открытие бронзового бюста Софьи Ковалевской. Восьмой раз собираются математики в Красноярске, при этом надо отметить, что популярность настолько велика и среди мужчин, что более 50 % докладов составляют «мужские». И сама идея проведения Конгресса принадлежала мужчине, зам. директора Института вычислительного моделирования СО РАН профессору Горбаню А.Н.
Мы видим, как много может сделать небольшая группа ученых, собравшись из разных научных и учебных учреждений, объединившись только одной целью - продвигать математику в Красноярске, в России и за её пределами. Ими учтено и то, что надо задействовать все моменты для достижения цели. Поддержать молодых ученых, а это значит провести конкурс научных работ, тем самым практически подобрать им возможных оппонентов на защиту диссертаций. Подержать учителей, пригласив их на мастер – класс и поделиться передовыми разработками, и, конечно же, подчеркнуть значимость ученых в теоретической и прикладной математике. Особенно важно это в сегодняшние дни, когда интерес к Царице наук Математике гаснет.
Удивительно разнообразна и тематика докладов на Конгрессе. Традиционно на каждом Конгрессе один из пленарных докладов посвящен С.В. Ковалевской, например: «О вращении твердого тела вокруг неподвижной точки в работе С.В. Ковалевской» (доцент Щепановская Г.И.); «Софья Ковалевская глазами современников» (профессор Проворова О.Г.); "Nomen est omen "(Turne L., г. Стокгольм); «Стандарты третьего поколения или русские женщины в науке» (доцент Адмаев О.В.); «Софья Ковалевская первая женщина-математик. Взгляд из наших дней» (профессор Захаров Ю.В.). Пленарные доклады дают толчок к новым идеям и решениям. «Геометрия пространств данных» (профессор University of Leicester Горбань А.Н.); «Четырехстадийная вычислительная технология в задачах аэродинамики» (член-корр. РАН, директор ИВМ СОРАН Шайдуров В.В.); «Эвентология и обобщенная теория неопределенности» (профессор Воробьев О. Ю.); «Моделирование рассуждений алгебраическими методами» (профессор Кулик Б.А.); «Космодром. Мне снится его рокот» (аспирант Вильямен В.).
Диапазон статей достаточно широк: есть информация и для размышления, и для обогащения педагогического опыта, и для обсуждения проблем и их решения. Будем надеяться, что они вызовут живой интерес к математике, её приложениям, и, конечно же, желание участвовать в работе следующего Конгресса.

Nanos-cience is of a cross-disciplinary nature which implies the necessity to use knowledge of various disciplines, i.e. there are ontologies of other domains in this ontology. The paper proposes a mathematical ontology model of the nanomaterials domain with complicated structures and terms from ontologies of organic chemistry and physical chemistry.

Adaptive prediction of wildfire behavior on the basis of aerospace monitoring
Author: Nezhevenko Еvgeniy Semenovich / Kozik Viktor Ivanovich / Feoktistov Аrtem Sergeevich
Description: A method of modeling a dynamic process on the Earth surface, for instance, a forest fire, with the use of a recurrent neural network is proposed. The learning process of the neural network, similar to the process of data assimilation in GIS technologies is described. A method of acceleration of neural network learning by using the Kalman filtration is proposed. The efficiency of its application is analyzed. The software implementation of the model based on fire recurrent neural network which simulate the process in real time is presented.
Keywords: computer simulation, wildfire, recurrent neural network, data assimilation, Kalman filter
