We consider the basic problems, notions and facts in the theory of
entire functions of several variables, i. e. functions J(z) holomorphic
in the entire n space 1 the zero set of an entire function is not
discrete and therefore one has no analogue of a tool such as the
canonical Weierstrass product, which is fundamental in the case n = 1.
Second, for n> 1 there exist several different natural ways of
exhausting the space
