Stretch and orientational mode decoupling in relaxation of highly stretched polymer melts
Physical Review Research, 2020 We study the relaxation of linear polymer molecules following fast uniaxial extension. Polystyrene melts of M_{w}=80 kg/mol are elongated at a Rouse-Weissenberg number Wi_{R}=1.5 to Hencky strain ɛ=3, where steady state is approached using a filament ...

Approximation on the sphere by weighted Fourier expansions
Journal of Applied Mathematics, 2005 The main theme of this paper is the approximation on the sphere by weighted sums of spherical harmonics. We give necessary and sufficient conditions on the weights for convergence in both the continuous and the LP cases.
