I liked the answer to this question: An algebra of "integrals" by @anixx Which had a very detailed table attached. My understanding is the answerer had updated the question some 35 times to generate this table/correct bugs Some commenters didn't appreciate this since they felt it was polluting th...
Let me try to mention a few things. Specifically, I want to concentrate on: Some statistics about bumping/editing. Already existing feature requests. What users already can do to avoid excessive bumping. Some statistics. SEDE contains various information about Stack Exchange posts, including th...
Assume $R$ is reduced and $\mathrm{min}(R)$, the set of minimal prime ideals, is finite. Then $R$ has a universal aic, one in which every aic of $R$ can be embedded. We show this below. Rings of this type have quite remarkable properties, and they include all Noetherian reduced rings. Domains are...
I am currently working on a similar system. But your properties (2) and (3) would not work and need change. Instead, the following properties would work much better: $$\int_a^c f(x) dx=\int_a^b f(x)dx+\int_b^c f(x)dx\tag{1}$$ $$\int_a^b (f(x)+g(x)) dx=\int_a^b f(x)dx+\int_a^b g(x)dx\tag{2}$$ $$\i...
It is not unusual that a single example or a very few shape an entire mathematical discipline. Can you give examples for such examples? (One example, or few, per post, please) I'd love to learn about further basic or central examples and I think such examples serve as good invitations to various...
The following picture illustrates a not unusual situation of intersections, in which the various components are assumed to have various fundamental groups: It helps here to have a theorem which immediately determines the fundamental groupoid of the union on these base points. Then one uses alge...
Mathematical notation in a given mathematical field $X$ is basically a correspondence $$ \mathrm{Notation}: \{ \hbox{well-formed expressions}\} \to \{ \hbox{abstract objects in } X \}$$ between mathematical expressions (or statements) on the written page (or blackboard, electronic document, etc.)...
