Star product deformation of the zeta function
One parameter deformation of function is given by means of convergent star product,
where the deformation parameter varies in some domain of $\mathbb C$.
The deformed functions are called {\it star functions}.
In this presentation, we give a short survey of
star product, especially as a simple case,
a star product of functions of one variable.
We discuss a deformation of the Riemann zeta function by the star product.
