On simple Shamsuddin derivations in two variables.
We study the subgroup of k -automorphisms of k [ x , y ] which commute with a simple derivation d of k [ x , y ] . We prove, for instance, that this subgroup is trivial when d is a shamsuddin simple derivation. in the general case of simple derivations, we obtain properties for the elements of this subgroup.
متن کاملNonholonomic Simple D-modules from Simple Derivations
We give new examples of affine sufaces whose rings of coordinates are d-simple and use these examples to construct simple nonholonomic Dmodules over these surfaces.
متن کاملOn Two Forms of Bureaucracy in Derivations
We call irrelevant information in derivations bureaucracy. An example of such irrelevant information is the order between two consecutive inference rules that trivially permute. Building on ideas by Guglielmi, we identify two forms of bureaucracy that occur in the calculus of structures (and, in fact, in every non-trivial term rewriting derivation). We develop term calculi that provide derivati...
متن کاملA Note on Simple Programs with Two Variables
It is well known that programs using only the following constructs: {x+x+ 1, X+-.X I 1, if x =0 then goto I, goto 1, halt} compute all partial recursive functions [7]. In fact, Minsky showed that simple programs with three variables compute all partial recursive functions with one argument and, consequently, simple programs with three variables recognize all recursively enumerable sets. We ask ...
متن کاملImages of locally finite derivations of polynomial algebras in two variables
In this paper we show that the image of any locally finite k-derivation of the polynomial algebra k[x, y] in two variables over a field k of characteristic zero is a Mathieu subspace. We also show that the two-dimensional Jacobian conjecture is equivalent to the statement that the image ImD of every k-derivation D of k[x, y] such that 1 ∈ ImD and divD = 0 is a Mathieu subspace of k[x, y].
