Deformations of A^1-fibrations
R. V. Gurjar, K. Masuda, M. Miyanishi
We consider log deformations of affine surfaces with fibrations by the affine lines. Such a fibration is of affine type (resp. of complete type) if the base curve of the fibration…
Algebraic derivations on affine domains
Kayo Masuda, Masayoshi Miyanishi
We observe algebraic derivations on an affine domain B defined over an algebraically closed field of characteristic 0, which are called locally finite derivations in commutative an…
-fibrations on affine threefolds
R. V. Gurjar, M. Koras, K. Masuda +2
The affine line minus one point is the underlying space of the algebraic torus of dimension one. However the fibration of an affine algebraic threefold by the affine line minus one…
Surjective derivations in small dimensions
R. V. Gurjar, K. Masuda, M. Miyanishi
Inspired by a result of D. Cerveau on surjective derivations on a polynomial ring in two variables over a complex number field C, we consider a surjective derivation defined on an…
