Abstract

In this paper, we introduce a new type &lt;italic&gt;λ&lt;/italic&gt;-Bernstein operators with parameter λ∈[−1,1]&lt;inline-graphic&gt;&lt;/inline-graphic&gt;, we investigate a Korovkin type approximation theorem, establish a local approximation theorem, give a convergence theorem for the Lipschitz continuous functions, we also obtain a Voronovskaja-type asymptotic formula. Finally, we give some graphs and numerical examples to show the convergence of Bn,λ(f;x)&lt;inline-graphic&gt;&lt;/inline-graphic&gt; to f(x)&lt;inline-graphic&gt;&lt;/inline-graphic&gt;, and we see that in some cases the errors are smaller than Bn(f)&lt;inline-graphic&gt;&lt;/inline-graphic&gt; to &lt;italic&gt;f&lt;/italic&gt;.
