P. Aubin, Un théorème de compacité, C.R. Acad. Sc. Paris, 256 (1963), pp. 5042–5044. It seems this paper is the origin of the "famous" Aubin–Lions lemma. This lemma is proved, for example, here and here, but I'd like to read the original work of Aubin. However, all I got is only a brief review (from MathSciNet).Mon, 13 Apr 2026 05:47:00 GMThttps://math.stackexchange.com/questions/2207334/como-calcular-el-area-de-la-superficie-de-un-huevo-con-calculo?noredirect=1&lq=1Estoy haciendo mi reciente evaluación interna del IB Matemáticas HL y mi tema es cómo calcular el área de superficie de un huevo . Quiero aplicar el cálculo conocimiento en esta pregunta, pero mi conocimiento sobre esta área es limitada.Mon, 13 Apr 2026 09:22:00 GMThttps://math.stackexchange.com/questions/3854661/study-of-the-sequence-un-defined-by-u-0-a-and-u-n1-a-frac1-b-n2Show that (Un) is bounded, convergent and find its limit. To prove that the sequence is bounded i intuitively used the fixed point theorem because at first glance i don't really know the appropriate way to study this sequence as it's neither arithmetic nor geometric or the both.Tue, 14 Apr 2026 14:21:00 GMThttps://math.stackexchange.com/questions/1336802/why-do-un-integrable-functions-existBy un-integrable I mean functions whose antiderivative can not be expressed in terms of elementary functions. I recently learnt that any differentiable function can be expanded using the Taylor expansion, which essentially provides a polynomial representation.Tue, 14 Apr 2026 17:34:00 GMThttps://math.stackexchange.com/questions/153902/un-countable-union-of-open-setsA remark: regardless of whether it is true that an infinite union or intersection of open sets is open, when you have a property that holds for every finite collection of sets (in this case, the union or intersection of any finite collection of open sets is open) the validity of the property for an infinite collection doesn't follow from that. In other words, induction helps you prove a ...Tue, 14 Apr 2026 19:50:00 GMThttps://math.stackexchange.com/questions/1777280/the-sequence-of-integers-1-11-111-1111-ldots-have-two-elements-whose-diffProve that the sequence $\ {1, 11, 111, 1111, .\ldots\}$ will contain two numbers whose difference is a multiple of $2017$. I have been computing some of the immediate multiples of $2017$ to see howSat, 11 Apr 2026 15:22:00 GMThttps://math.stackexchange.com/questions/3397714/can-you-describe-all-the-ways-to-un-localize-a-ringYou might consider the word "globalize" rather than "un-localize". This term is used in number theory and algebraic geometry, for instance in Ravi Vakil's or Eisenbud-Harris's books.Mon, 30 Mar 2026 02:36:00 GMThttps://math.stackexchange.com/questions/2067272/limit-sequence-un-and-vnLimit sequence (Un) and (Vn) Ask Question Asked 9 years, 3 months ago Modified 9 years, 3 months agoMon, 06 Apr 2026 04:08:00 GMThttps://math.stackexchange.com/Q&A for people studying math at any level and professionals in related fieldsFri, 27 Mar 2026 00:09:00 GMT
