On the injectivity of certain homomorphisms between extensions of $G^^{(λ)}$ by $G^_{m}$ over a $Z_{(p)}$ -algebra

Michio Amano

Let $G^{(λ)}$ be a formal group scheme which deforms $G_{a}$ to $G_{m}$ . And let $ψ^{(l)}:\widehat{\mathcal{G}}^{(λ)}\rightarr…

The surface of circumferences for Jenkins-Strebel differentials

Masanori Amano

There are some existence problems of Jenkins-Strebel differentials on a Riemann surface. The one of them is to find a Jenkins-Strebel differential whose characteristic ring domains…
