Query: Soliton Fermionic number from the heat kernel expansion   We consider different methods of calculating the (fractional) fermion number
of solitons based on the heat kernel expansion. We derive a formula for the
localized eta function a more systematic version of the derivative expansion
for spectral assymmetry and that provides a more systematic version of the
derivative expansion for spectral asymmetry and compute the fermion number in a
multiflavour extension of the Goldstone-Wilczek model.We also propose an
improved expansionof the heat kernelthat allows the tackling ofthe convergence
issues and permits an automated computation of the coefficients
