There are some known solutions for 3D Navier-Stokes such as Beltrami flow.
In the literature these Beltrami flow solutions are said to not take into account viscosity, however when I read the information on Beltrami flow, they do seem to involve (kinematic) viscosity:
From incompressible...
It seems you are confusing two things, you might have seen some videos that hypothesize the further evolution of our universe, that after trillions and trillions of years, all matter falls into black holes and even evaporates, leaving nothing but empty space. This "ending" doesn't necessarily...
Cosmic inflation is a major point behind the idea of the Big Bang, since that interpretation of the redshift/hubble constant (inflation) still holds strong, Big Bang remains a reasonable possibility. Regarding the mature galaxies , I am not aware but there is possibly an explanation within Big...
I believe you are correct in that is the most famous example and still being lectured today (saw one a week ago from IAS). I can reference you to a nice talk given by Alejandra Castro regarding 3D+1 Chern-Simons theory and also in relation to AdS/CFT , she talks about the gravity connection...
I think we should stick with 4-D spacetime too, in connection to AdS/CFT I believe 3+1 chern-simons is used for this gravity explanation, but I find it unclear as to what the gravity dynamics actually are ["gauge/connection" etc] and if it comes anywhere close to experimental measurements. I...
I saw that the paper employed some numerical programming methods that I am aware of, and that might be fruitful to try out and test, possibly some have never been tried before with certain groups for the gauge/gluons. Maybe some cool bachelor project or more.
Yes I know quite some females are...
Do you remember which dihedral group this is, or is that related to every dihedral group (and about the double cover comment) ? Cause there are quite a few.
A 3D dimensional manifold, which SO(3) is too, seems to me that it fits the best to reality ?
Actually it is quite interesting IMO.
Here are a few papers that relate quark/gluon flavor symmetries to discrete groups

Thank you sir, yes it is much more clear now, and thank everyone for your answers. Basically for a dihedral group to be applicable, it would require a different approach altogether than QCD...
CAn you explain why it is a hard requirement for it to be a Lie group ? Or is it built in/basically...
