```
The conductivity equation
```

```
is equivalent to:
```

```
for potential
```

For an analog of this system on e-networks, one defines the solution of the Schrodinger equationuon the nodes and the square of the conductivity on the edges by the following formula: <math>\c^2(a,b) = x(a)x(b).

**Exercise (**).**Reduce the inverse problem for the Schrodinger equation on domain to the conductivity equation one with conductivity c.
