摘要 研究了正交Euler-Lagrange型三次方程Ef(x,y)f(mx+y)+f(mx-y)-mf(x+y)-mf(x-y)-2m(m2-1)f(x)=0在混合型积和函数F(x,y)=ε{xEpypE+(xE2p+yE2p)}和泛函H(x,y)限制下的Ulam稳定性. We investigate the Ulam stability of the orthogonally Euler-Lagrange type cubic functional equation Ef(x,y) f(mx+y)+f(mx-y)-mf(x+y)-mf(x-y)-2m(m2-1)f(x)=0 controlled by the mixed type product-sum functional F(x,y)=ε{ x pE y pE+( x 2pE+ y 2pE)} and a functional H(x,y),respectively.
