Plane Curve Singularities,rsection multiplicity of two (irreducible) plane curve singularities (., o) and (., o). This number can be calculated as follows. Consider the normalization ?{.} of .., and let (., o) be given by . = 0. Via the inclusion .. ∈?{.}, we can consider at . as an element of ?{.}. Then the intersection mul

Classification of Simple Hypersurface Singularities,acy Theorems. Let m be the maximal ideal of ?{..,... ,..}. A function / is called (right) .-determined if for all elements . with . ∈ m.. the functions / and . are right equivalent. In particular, a .-determined . is right equivalent to a polynomial of degree at most .. A function is called finitely

The most prominent and important example is the substitution of division with remainder. Its substitution in local analytic geometry is called

As one often reads in prefaces of int- ductory books on algebraic geometry, it is not so easy to develop the basics of algebraic geometry without a proper knowledge of commutative algebra. On the other hand, the commutative algebra one needs is quite difficult t

Approximation Theorems, system of analytic equations has a formal solution (which is sometimes really not convergent) then we can find a convergent solution to this system. Even more, we can approximate the formal one by convergent ones up to a given order.
