摘要:
In this paper the authors give a definite meaning to any formal
trigonometrical series and generalize it to an abstract Hilbert space.
Then in the case L2(-∞,+∞) they discussed extensively the
generalized expansion problem by Hermite functions, and applied to a
non-strictly nonlinear hyperbolic system.
