What functions can be obtained as a convolution of a Schwartz function and a tempered distribution?
Would you mind to show the argument? |

$\ell_o$ Minimization (Minimizing the support of a vector)
Still a question remains: What is the aim of your reformulation? In other words: what is wrong with the $\ell^0$-minimization problem? As you have written: The problem is NP-hard and hence, there will be no "easy" reformulation with out any further assumption on $A$ (unless $P=NP$). |

$\ell_o$ Minimization (Minimizing the support of a vector)
I am confused: Do you look for an exact reformulation or an LP relaxation? |

Way to memorize relations between the Sobolev spaces?
Isn't that the "DeVore-diagram"? |

Does the minima of a sequence of convex convergent functions converge?
By the way: The proper notions for convergence of minimizers is Gamma convergence: en.wikipedia.org/wiki/%CE%93-convergence. |
