- Abstract
The asymptotic formulae of approximation of multivariate unbounded continuous functions is studied. By using the method of multiplier-enlargement, the asymptotic estimation of approximation of multivariate unbounded continuous functions with positive linear operators is discussed , and general asymptotic formulae is given. As an example, the asymptotic formulae of approximation of multivariate unbounded continuous functions with Landau operators are discussed, and therefore some conclusions of professor Hsu Lizhi are generalized.
