Formal power series (Part 1)
At the seminar we will discuss the following statement of M. Artin:
Let 3d0202424.png)
be analytic equation (
is analytic). We will show that if the equation has a solution 202424.png)
in the space of formal series than it has also analytic solution which differs from 20202424.png)
coefficients with large powers.
