Research Abstract

We, M. Hickel, T. Ito and I, succeeded to prove Diophantine inequality forexcellent Henselian domains, this may be the most general kind of local ringsfor the inequality. Next, I gave an algebraic explanation and a generalisationof the singularities of embeddings of plane algebraic curves found by Bos andCalvi. Using this theory, I have obtained an estimate of transcendency index ofanalytic curves enbedded in affine spaces.
