A Necessary Condition for Admissibility

A necessary condition for a Shearlet system to be a frame via admissibility

    Necessary conditions for  shearlet  and cone-adapted shearlet systems to be frames are presented with respect to the admissibility condition of generators.

A Necessary Condition for Weyl-Heisenberg Frames

Proof of a Necessary and Sufficient Condition for Admissibility in Discrete Multivariate Problems*

The proof of Farrell (1968. Ann. Math. Statist. 26 518-522) is adapted to the special problems presented by discrete problems. Continuity of the risk functions is veritied, sequential subcompactness is verified, and a necessary and sufficient condition for admissibility proven. In the discrete problems considered one obtains pointwise convergence of the sequence of Bayes estimators to the admis...

A necessary condition for multiple objective fractional programming

In this paper, we establish a proof for  a  necessary condition for  multiple objective fractional programming. In order to derive the set of necessary conditions, we employ an equivalent parametric problem. Also, we  present the related semi parametric model.
