Detailed proof of the Jacobian theorem: existence of suciently many special sequences.
Note rst that if R itself is a eld then S = L and S = S, so that JS/R = JS /R and
there is nothing to prove. If R is nite then R mu

The Tukey 1-df Test for Nonadditivity
How does a regression of the observed data against the squares of its predicted values tell you anything
about the existence of nonadditive effects? One way to think about it:
To begin, recall that under our linear mo
How can I test for nonadditivity in a randomized block ANOVA in Stata?
Randomized block ANOVA models assume additive block and treatment effects, that is, that
there is no treatment by block interaction. Tukey's test for nonadditivity is a one degree of

(a) If M has a nite ltration with factors Nj , 1 j s, and x is a nonzerodivisor on
every Nj , then M/xM has a ltration with s factors Nj /xNj , and M/xn M has a

One of our goals is to discuss what is known about the following conjecture of C. Lech,
which has been an open question for over forty years.
Conjecture. If R S is a at local map of local rings, then e(R) e(S).
This i

Discussion: the dierence operator. Consider the ring Q[n] of polynomials in one variable
n over the rational numbers. We dene a Q-linear function from this ring to itself by
P (n) = P (n 1). Note that preserves degre

We have completed the proof of the theorem on comparison of symbolic powers of prime
ideals in regular rings as soon as we have established:
Lemma. Let P be a prime ideal of the ring R that is generated by a regular s

Before attacking the problem of comparing symbolic powers of primes, we want to
discuss some techniques that will be needed. One is connected with enlarging the residue
class eld of a local ring.
Proposition. Let (R,

To nish our comparison of symbolic powers in a regular ring, we shall make use of
quadratic transforms (also called quadratic transformations or quadratic dilatations) in a

A critical Lemma and the nal step in the proof.
The following result of Lipman and Sathaye is exactly what is needed to establish that
WS/R decreases as S is increased by adjoining integral fractions.

Examples. Let R = K[x, y]/(x2 , xy). This ring has a unique minimal prime, xR, and
m = (x, y)R is embedded. The image x of x in the ring generates a submodule isomorphic
to R/m, which has lower dimension. Then e(R) =

If I J and J is integral over I, we call I a reduction of J. With this terminology, we
have shown that if (R, m, K) is local with K innite, every ideal I m has a reduction
with an(I) generators, and one cannot do bett

We showed in the Lecture of October 9 that the map ,g is injective. We next want to
show that its image WS/R (, g) is indepedent of the choice of the presentation and the
choice of special sequence g.
