@janhardo  wrong -this two theta ^2 are extra

@janhardo  this is wrong the function don't have exponential even! 

@janhardo your ai define the function inside the proc, you have to use N-soliton series then have to idea first do change of variables then apply limit epsilon-->0 or k[1]-k[2]-->0

@janhardo  all wrong except F[3] which already define in procedure, thanks john take some rest

@janhardo i watched is totaly wrong becuase you write the function we already define and just add so it is wrong we have to apply something to N-soliton series to get F[1],F[2],F[3],F[4],F[5] in here we didn't apply long wave limit if you watch the procedure it use fucntion which already write down so don't have mean like that we don't reach out point i will search more and try to apply limit and tylor series

@janhardo  for N=4 we have this function 

@janhardo  this function is true i want other be like that can we do that?

LumpSolitonTauFunction(3);
 ((B23 + theta2) theta1 + B13 B23 + B13 theta2 + B12) exp(eta3)

    + theta1 theta2 + B12

@janhardo this true but How reach this is so perfect you get F[3] can you test for N=2 and N=4 N=5 we have that and if it is true then it is done!

@janhardo i don't want N-soliton i want apply long wave limit  with tylor series to N-soliton solution to get that function  F[3] function F[3] is example but apply first for N=2 is more esier the F[2]=theta[1]*theta[2]+B[12] if we get this then we can do for N=3,4,5,6,...

@janhardo  if N=3 we have to get this 

@janhardo in F[3] i mention in picture in top have exponential we have to apply long wave limit just for k1-k2-->0 and other remain so how we do that?

@janhardo  no thus code are useless i have my own code but they are so complicated and have a lot of part because of that I can't upload here , i know all part to change it  but i don't know where is mistak , if you give my code to your ai maybe ai can finish the work

@janhardo  he use that function i give it in picture, i want acheive them by that substitution i mentioned and apply   long wave limit and   apply series so How we can reach this the F_2 is easiest one if you can reach F_2  when N-2 we have F_2=theta[1]*theta[2]+B[1,2] if you find this you will find other first try find this then you can reach other too also i mentioned a file of series in top why didn't use that series i will upload here too 

N-S.mw

@janhardo  this is some of that function when k[1]-k[2]-->0 

@janhardo  i have in paper i have function untill F_5 after applying long wave limit  can you do that ? this is great answer he did this is exactly we want
