Volume 04, Issue 01 , February 2015, , Pages 25-34

##### Abstract
We give some new results on sparse signal recovery in the presence of noise, for weighted spaces. Traditionally, were used dictionaries that have the norm equal to 1, but, for random dictionaries this condition is rarely satisfied. Moreover, we give better estimations then the ones given ...  Read More

##### $\mathcal{E}$-metric spaces and common fixed point theorems

F. Yousefi; H. Rahimi; G. Soleimani Rad

Articles in Press, Accepted Manuscript, Available Online from 29 July 2022
