On the Performance of Sparse Recovery Via $\ell_p$-Minimization $(0 \leq p \leq 1)$

IEEE Transactions on Information Theory, 2011
It is known that a high-dimensional sparse vector x* in TV can be recovered from low-dimensional measurements y = Ax* where Am×n(m

The L p -Approximation Order of Surface Spline Interpolation for 1 \leq p \leq 2

Constructive Approximation, 2004
The author studies the problem of \(L_p-\) approximation order of surface spline interpolation. In [Constructive Approximation 14, No.3, 429-438 (1998; Zbl 0904.41005)] and [Math.Comp. 70, No.234, 719-737 (2001; Zbl 0973.41005)] respectively, the author obtained upper and lower bounds for the \(L_p-\) approximation order of surface spline interpolation.

A contact condition for $p$ -codimensional submanifolds of a symplectic manifold ( $2\leq p\leq n$ )

Mathematische Zeitschrift, 1998
Let \((M, \omega)\) be a \(2n\)-dimensional symplectic manifold. A smooth submanifold \(S_p\) of \(M\) of codimension \(p\) \((1\leq p\leq n)\) is said to be coisotropic if \(\text{Ker} \omega |_{S_p}\) is \(p\)-dimensional everywhere on \(S_p\). The author defines a \(p\)-contact condition for any coisotropic submanifold \(S_p\) of a symplectic ...

Super-and hyper-deformed nuclei for 58 $\leq$ Z $\leq$ 92

1992
A systematic occurrence of the super‐ and hyper‐deformed nuclear configurations is illustrated for 58≤Z≤92 nuclei. The cases selected correspond to the most stable among those exotic configurations. Here we arbitrarily qualify the configurations as ‘‘reasonably stable’’ if the corresponding minima on the total energy surfaces are surrounded by the ...

Sharp counterexamples related to the De Giorgi conjecture in dimensions $4\leq n \leq 8$

Proceedings of the American Mathematical Society, 2013
The following problem concerning Liouville comparison principle is known to be closely related to the celebrated De Giorgi conjecture: Let \(\varphi\) be a strictly positive function on \(\mathbb{R}^n\), and consider the divergence form operator \(L=- \nabla\cdot (\varphi^2\nabla)\) on \(\mathbb{R}^n\).
