J. Gregory et Hr. Hughes, A GENERALIZED APPROXIMATION-THEORY FOR QUADRATIC-FORMS - APPLICATION TO RANDOMIZED SPLINE TYPE STURM-LIOUVILLE PROBLEMS, Journal of theoretical probability, 8(3), 1995, pp. 703-715
An approximation theory for families of quadratic forms is given. We s
how that if continuity conditions for a family of quadratic forms hold
uniformly on an index set for the family, generalized signature appro
ximation results hold. We then apply these results to randomized splin
e type Sturm-Liouville problems and obtain continuity of the nth eigen
value for generalized Sturm-Liouville problems under weak hypotheses.
