Семинар “Алгебра и логика”
ZoomНа 19 март 2021 г. (петък) от 16:00 часа ще се проведе дистанционно заседание на семинара по „Алгебра и логика”. Доклад на тема Some applications of transfinite numbers to algebra and some applications of number theory to transfinite numbers ще изнесе Andreas Weiermann (Ghent University, Belgium). Резюме. In the first part we will survey the role of transfinite numbers in the study of Hilbert's basis theorem and its extension by MacLagan. To this end we associate ordinals to some natural well partial orderings related Cartesian products of the set of natural numbers and we apply this apparatus to monomial ideals in F[X_1,...,X_n] where F is a field. In the second part we use the machinery of Tauberian theorems to prove some structural results about transfinite [...]
