SUMMARY OF RESEARCH WORK :
We have worked on the following problems. The first problem is the Laurent polynomial analogue
of the corresponding theorem in polynomial rings proved by Satya Mandal.
Problem 1 : Let I be an ideal of the Laurent polynomial ring A[T, T−1] containing a doubly monic poly-
nomial. Let P be a projective A-module of rank r dim(A[T, T−1]/I)+ 2 and suppose that S : P −!
I(1) and : P[T, T−1] −! I/I2 are surjective homomorphisms such that (1) S mod (T −1, I(1)2).
Then there is a surjective homomorphism : P[T, T−1] −! I such that (1) = S and lifts .
Problem 2 : Suppose A is a commutative Noetherian ring and I is an ideal in the polynomial algebra
A[T] containing a monic polynomial. Suppose also that µ(I/I2) = r dim (A[T]/I) + 2. Assume
that I(0) is generated by r elements, say, a1, ..., ar.
(i) Can we find a set of generators f1, ..., fr of I such that fi(0) = ai, for all i = 1, · · · , r?
(ii) Can we find a set of generators of I in which one and hence all the generators are monic ?
We settle the problem 1 in a rmative. The problem 2, in general, has negative answer. We have
given examples to show this. However in certain cases result is true and interesting. In some cases
answer is complete and in some cases answer is partial. We have answered the question in the following
cases:
(1) A is semi local Noetherian ring and I(0)/I(0)2 is a free module over A/I(0) with I(0) Rad(A).
(2) A is local Cohen Macaulay ring and I(0) is a local complete intersection ideal of A.
(3) I is a zero dimensional ideal.
(4) I is a local complete intersection ideal of height r = dim(A[T]).
(5) µ(I/I2) = 1 and A is an integral domain.
(6) I(0) = I(0)2.
In some cases the Laurent polynomial analogue are also proved.
Problem 3 : We have extended the famous theorem of Quillen to the graded ring.(Expositiones
Mathematicae, Elsevier Publication, Vol. 22, 2004. 29-30)
Let S = ∞
i=0Si be a graded ring and let M be a finitely presentable S-module, which is a locally
extended, for all M2 Max (S0). Then M is a globally extended.
Problem 4 : Primary decomposition over rings graded by finite abelian groups (With Markus Perling)
(Journal of Algebra, 318(2), 2007, 553-561.)
Let R be a Noetherian ring which is graded by a finite abelian group G. In general, for G-graded
R-modules there do not exist primary decompositions which are graded themselves. This is quite
di erent from the case of gradings by torsion free group, for which graded primary decompositions
always exists.
In this paper we introduced G-primary decompositions as a natural analogue to primary decom-
position for G-graded R-modules. We show the existence of G-primary decomposition and give a few
characterizations analogously to Bourbaki’s treatment for torsion free groups.
Problem 4 (International Journal of Algebra, 2009) : We have given di erent versions of
Bertini’s theorems and proved following a variant of theorem of Bertini.
• Let A be a finitely generated K algebra with K characteristic 0, algebraically closed field. Assume
A reduced and dim(A) 2. Let f, g 2 A with that ht(f, h) 2. Then for all but a finite number
of 2 K, A/(f + h) is reduced.
We used this theorem to prove the following :
• Suppose A is a semilocal regular reduced a ne algebra over an algebraically closed field of
characterstic zero such that every maximal ideal in A[T] is complete intersection, with dim(A) =
n > 0. Suppose I is an ideal of A[T], with height(I) = n + 1. Assume co-normal module I/I2
is generated by n + 1 elements over A[T]/I. Then we can find a minimal set of generators of I
with a monic polynomial.
