On a space of entire functions rapidly decreasing on ${\mathbb{R}}^n$ and its Fourier transformation

A space of entire functions of several complex variables rapidly decreasing on ${\mathbb{R}}^n$ and such that their growth along $i{\mathbb{R}}^n$ is majorized with a help of a family of weight functions is considered in the paper. For this space an equivalent description in terms of estimates on all partial derivatives of functions on ${\mathbb{R}}^n$ and Paley-Wiener type theorem are obtained.
