We describe an algorithm which computes the invariants of all \(G_{a}\)-actions on affine varieties, in case the invariant ring is finitely generated. The algorithm is based on a study of the kernel of a locally nilpotent derivation and some algoritlums from the theory of Gröbner bases.
Let A be an abelian variety of GL 2 -type over the rational number field Q, without complex multiplication. In this paper, we will show that a modularity of A over the complex number field C implies that of A over Q.
The relationship between the geometrical structure of a canopy layer and the bulk transfer coefficient was investigated using a numerical canopy model. The following results were obtained: (1) The bulk transfer coefficients for momentum and heat, CM and C,, change with non-dimensional canopy densit
A canopy flow coupling parameter is defined from earlier canopy flow research to describe the degree of coupling of air flow in vegetation to ambient flow of the surface boundary layer. This ratio concept employs an exponential wind-height relationship in the canopy referenced to the logarithmic win
