@mercio: Bonjour! Today would be a good day for me to finish this MS. Do you think you'll be able to complete your corrections by noon today?

sorry I don't have as much time today, but I can finish it this evening

though if my friend doesn't show up maybe i can finish it now

what do you mean it's lunch time

I sent you something for now

I rewrote much of the intro of the mat hsection

the tug of war for point group is a subgroup of O(3) with a representation of itself into O(3) is still going on

and I think there was a typo I noticed in the earlier sections but I coudln't find it again

also I harmonized the JTT formulation to match the edkhard wigner theorem

great thanks a lot!!

I was quite busy now. I'll continue working on it!

@mercio Its getting a nice ms. A question do you feel motivated/able to make a nice table of all point groups in sections acc. to the three famlies, and then with all deg. IR, the corresponding Alt^2 and Gamma_l_(z)? In case it would be very helpful. Otherwise I'll do it. But it may take a while, I have busy weekend ...

I think I can do that for the nonisometric groups, for the isometric point group it would be a bit more painful and less useful I think

if you also want the whole character tables it will be annoying to format for the infinite families

also I won't call the conjugacy classes the same way as you do

(cuz I don't want to write the same table several times with different names)

@mercio really? Its only 7 of them while for the non-isos you have the nuissance with odd and even orders, at least that was my impression. And I thought it would be good to see what Alt^2 is for the isometric. No the whole character tables are not needed. It would be quite nice if there would be a nice way to compress everything in one table.

As I wrote for each group all IRs with dim > 1 (over R), their respective Alt^2 and the IR for l or l_z. But that would be cool. And big separators K_aaa, K_ae, K_t then we don't need to enumerate them in the ms (+ we have an impressive table ... ;-) )

I think one would have the group names in the first column, then something like a double line first E_x, second Alt^2(E_x) and somewhere the Gamma_lz

and maybe there is a way to condense even different point groups in one line I dunno like Cn(v/h) ...

just an idea
