Vanilla 1.1.10 is a product of Lussumo. More Information: Documentation, Community Support.
brief entry to go with the list of experiments, and to record today’s
I have expanded a bit at bilinear map, trying to add a pedagigical comment on the difference to a group homomorphism
created this page in connection with topology - countability axioms.
Created page in connection with open covers of metric spaces have open countably locally discrete refinements.
Created this page in connection with topology - countability axioms.
created genus of a number field
Added it to the function field analogy –table. Accordig to the footnote on the first page of Mazur-Wiles 83 the definition of this in Weil 39 is the origin of the function field analogy.
starting some minimum here , for the moment I just need a place to record references on dyonic membranes…
Created Sasakian manifold. This seems vaguely related to conifold/-manifold stuff, but the state of the art in the Sasakian world seems very much experimental: difficult to find any large families of such structures.
brief category:people
-entry for hyperlinking references at special orthogonal group and spin group
have created crystalline site
Since gravitational constant was there, I wrote in it.
Created in context of topology - global countability axioms.
brief category:people
-entry for hyperlinking references at Sp(n).Sp(1)
new entry spectral sequence of a filtered complex, !included into the correct section of spectral sequence. Doubtless still needs tidying.
Created page on this property in connection with Nagata-Smirnov metrization theorem.
I added some more material and references to separable space. Partly this was just to record a MO discussion which would otherwise get eventually buried under centuries of MO sediment, but I’ve included some other things as well. (E.g., I wasn’t aware until now that a product of continuum many separable spaces was still separable.)

But I was really looking for a solid reference for the basic statement that the maximal compact subgroup of is .

a bare minimum, for the moment just so as to record this references:
Moved from main Initiality Project page.
added entry for Agnès Beaudry getting rid of a grey link.
added pointer to
the book is finally out: springer:book/9783030047375
The proof of the fundamental theorem 3.9.4 of renormalization via addition of counterterms is in “essential parts” (footnote 118) taken from the Lab page geometry of physics – perturbative quantum field theory
started some minimum, so that our table exceptional spinors and division algebras – table can point somewhere
