Derivations and Bounded Nilpotence Index
International Journal of Algebra and Computation, 2015We construct a nil ring R which has bounded index of nilpotence 2, is Wedderburn radical, and is commutative, and which also has a derivation δ for which the differential polynomial ring R[x;δ] is not even prime radical. This example gives a strong barrier to lifting certain radical properties from rings to differential polynomial rings.

GEOMETRIC BOUNDS ON THE RELATIVE INDEX
Journal of the Institute of Mathematics of Jussieu, 2002The author introduces the notion of the relative index for a pair of embeddable CR structures. Let \((Y,{\xi})\) be a contact 3-manifold with the contact structure \(\xi\). Let \(J,J^{\prime}\) denote a pair of embeddable CR structures on \(Y\), compatible with \(\xi\).

Bounded index exponential hashing
ACM Transactions on Database Systems, 1983Bounded index exponential hashing, a new form of extendible hashing, is described. It has the important advantages over most of the other extendible hashing variants of both (i) providing random access to any record of a file in close to one disk access and (ii) having performance which does not vary with file size.

Journal of Mathematical Chemistry, 2009
In this paper, we obtain the lower and upper bounds on the Harary index of a connected graph (molecular graph), and, in particular, of a triangle- and quadrangle-free graphs in terms of the number of vertices, the number of edges and the diameter.

Bounds on the edge version of the Nirmala index
Discrete Mathematics, Algorithms and ApplicationsThe edge version of the Nirmala index is defined in terms of edge degrees as [Formula: see text], where [Formula: see text] denotes the degree of the edge [Formula: see text] in graph [Formula: see text] and [Formula: see text] means that the edges [Formula: see text] and [Formula: see text] are adjacent. In this paper, we obtain some sharp bounds for

Inflation Indexation and Zero Lower Bound∗
This study quantitatively assesses both the aggregate and disaggregate effects of inflation-indexed loan contracts using a heterogeneous agent New Keynesian (HANK) model with an occasionally binding zero lower bound (ZLB). Substituting real for nominal government bonds reduces the volatility of output and inflation and decreases the frequency of ZLB ...Daeha Cho, Eunseong Ma
