1. **Local Coordinates:** Near degeneration points (e.g., \(u^i \to 0\)), periods of \(\Omega\) behave exponentially. 2. **Monodromy:** SL(2,\(\mathbb{Z}\)) action suggests logarithmic map: \(t^i = \frac{1}{2\pi i} \log u^i = a^i + i s^i\), with \(a^i\) axionic (periodic) and \(s^i \to \infty\) as \(u^i ...
