A Note on Elementary Derivations
Let R be a UFD containing a field of characteristic 0, and Bm = R[Y1, . . . , Ym] be a polynomial ring over R. It was conjectured in [5] that if D is an R-elementary monomial derivation of B3 such that kerD is a finitely generated R-algebra then the generators of kerD can be chosen to be linear in the Yi’s. In this paper, we prove that this does not hold for B4. We also investigate R-elementary...
متن کاملA note on positivity of elementary operators
We show that operators on n×n matrices which are representable in the form T (X) = ∑` i=1 aiXbi (for ai and bi n×n matrices) and are k-positive for k = [ √ `] must be completely positive. As a consequence, elementary operators on a C*-algebra with minimal length ` which are k-positive for k = [ √ `] must be completely positive. For A a C*-algebra, an operator T :A→ A is called an elementary ope...
متن کاملNote on Some Elementary Properties of Polynomials
(4) cf ^ 2(1 d) >\ Equality holds only for f(x) = 1— x, a= — (1 —d). Suppose there exists a polynomial of degree n>2 satisfying (1) with Cf ̂ 2 ( 1 — d)\ then we will prove that there exists a polynomial of degree n — 1 with Cf >2(1 —d); and this proves (4) since it is easy to prove that (4) is satisfied for polynomials of second degree, that is, for l -# 2 . Denote the roots off(x) by Xi = — 1,...
متن کاملA Very Elementary Presentation of the Hannenhalli-Pevzner Theory
In 1995, Hannenhalli and Pevzner gave a first polynomial solution to the problem of finding the minimum number of reversals needed to sort a signed permutation. Their solution, as well as subsequent ones, relies on many intermediary constructions, such as simulations with permutations on 2n elements, and manipulation of various graphs. Here we give the first completely elementary treatment of t...
متن کاملA Very Low Voltage 9th Order Linear Phase Baseband Switched Capacitor Filter (RESEARCH NOTE)
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...
