— We show that (i) the Pythagoras number of a real analytic set germ is the supremum of the Pythagoras numbers of the curve germs it contains, and (ii) every real analytic curve germ

Nevertheless it is quite interesting to notice that given any algebra of formal power series which is closed under composition (as it should if one whishes to study conjugacy

If G is a Lie subgroup of some complex group H, then G is holomorphi- cally extendable. In particularly, every Lie subgroup of a holomorphically extendable group is

X is said to be strictly q-pseudoconvex if X is a relatively compact open subset of another complex manifold and if locally the boundary of X is defined by the vanishing of

For A = k, the analytic A-modules are exactly the vector A-spaces of finite dimension, and the canonical topology of an analytic A-module M is then the unique HausdorfY

Translation domains. In the Glutsyuk point of view, the admissible strips are placed parallel to the line of holes, i.e.. Let us considerfor instance Q 0 +,ε above the principal

The idea, in hyperbolicity questions, is that global sections of this bundle vanishing on ample divisors provide algebraic differential equations for any entire curve f : C →

In fact, we prove in the next section that U is analytic, using a different expansion obtained by arborification, and that appears to be normally convergent.... Analytic part
