Bernstein and Goodman showed that natural inequality ( NI) queries can be processed efficiently by semijoins, if there are no multiple inequality join edges, nor cycles with one or zero doublet. In this paper procedures to hand1 e these cases efficiently are given. Multiple inequality join edges can be processed by multi-attribute inequality semijoins. Two procedures based on generalized semi-j...

Semi-structured data, including but not limited to structured documents, has speci c characteristics and is used in ways di erent to tabular data. SGML and XML are widely used to represent information of this type. The demands on systems that manage semi-structured data vary from those on traditional relational systems. This paper reviews the nature and characteristics of semi-structured data, ...

The paper studies the connections and differences between bilevel problems (BL) and generalized semi-infinite problems (GSIP). Under natural assumptions (GSIP) can be seen as a special case of a (BL). We consider the so-called reduction approach for (BL) and (GSIP) leading to optimality conditions and Newtontype methods for solving the problems. We show by a structural analysis that for (GSIP)-...

In this paper, we have studied warped products and multiply warped product on quasi-Einstein manifold with semi-symmetric nonmetric connection. Then we have applied our results to generalized Robertson-Walker space times with a semi-symmetric non-metric connection.

We show that quadratic growth of a semi-algebraic function is equivalent to strong metric subregularity of the subdifferential — a kind of stability of generalized critical points. In contrast, this equivalence can easily fail outside of the semi-algebraic setting.

In this paper, we introduce three new types of generalized convex functions, called semi E-pseudoinvex, strictly semi Epseudoinvex and semi E-quasiinvex functions. Then some of their basic properties are studied, We used directional derivative and obtain the new results in this class of functions. As applications of our results, we obtain optimal solutions for multiobjective programming. AMS Su...

Abstract The generalized Broer-Kaup-Kupershmidt (generalized BKK) isospectral problem, including the x-derivative of potential, is considered based on Lie algebra A1. The variational trace identity is extended to construct Hamiltonian structure of generalized BKK system. The Lie algebra A1 is extended to the non-semi-simple Lie algebra of 4 × 4 matrix form, from which a hierarchy of soliton equ...
