lamda(eta) = eigenvalues of eta e = eigenvector of eta
B = left cauchy-Green tensor
lamda(b) = eigenvalues of B
I don't really know where to start. I've come up with this so far:
inv(B)e = (1-2lamda(eta))e
Any tips what to do?
I think it's pretty hard to understand your symbols: either you write in LaTeX, or else call E instead "eta", w instead lambda or the like.
