g-frames in hilbert spaces are a redundant set of operators which yield a repre-sentation for each vector in the space. in this paper we investigate the connection betweeng-frames, g-orthonormal bases and g-riesz bases. we show that a family of bounded opera-tors is a g-bessel sequences if and only if the gram matrix associated to its denes a boundedoperator.

conclusions consequently, small diameter scnt interaction with nucleic acid bases is noncovalent. also, the results revealed that small diameter scnt interaction especially scnt (4, 4) with nucleic acid bases can be useful in practical application area of biomedical fields such detection and drug delivery. objectives hence, the quantum mechanics (qm) method based on ab initio was used for this ...

The computational complexity of general change of basis algorithms from one bivariate polynomial basis of degree n to another bivariate polynomial basis of degree n using matrix multiplication is O(n 4). Applying blossoming and duality, we derive change of basis algorithms with computational complexity O(n 3) between two important classes of polynomial bases used for representing surfaces in CA...

This paper deals with the revision of partially ordered beliefs. It proposes a semantic representation of epistemic states by partial preorders on interpretations and a syntactic representation by partially ordered belief bases. Two revision operations, the revision stemming from the history of observations and the possibilistic revision, defined when the epistemic state is represented by a tot...
