摘要：

It is the purpose of this paper to investigate the stability problem of Ulam for an approximate mapping for the following generalized quadratic functional equation: Sigma(n)(i=1)Q(Sigma(j not equal 1)x(j) - (n - 1)x(i)) + nQ (Sigma(n)(i=1)x(i)) = n(2) Sigma(n)(i=1)Q(X-i) for all x(i) (i = 1,..., n), where n > 1.
