Minimizing mixed-norm subject to a nonconvex quartic constraint for small n and m
$begingroup$
How can one solve this mixed-norm minimization problem subject to a quartic constraint for small N and M (ex: M=12 and N=4):
- $textbf{c} = [c_{1},...,c_{N}]^T$
- $minbiggl (|textbf{c}|_{1} + beta|textbf{c}|_{2} ^2biggr) subjectspace
tospace sumlimits_ {m=1} ^M (|v_ {m} |^2-textbf{c}^Htextbf{a}_mtextbf{a}_m^Htextbf{c})
^2leqepsilon$
Thank you for advance for any suggestions.

This is not a convex problem, so you should remove that tag

Thank you for your comment. The problem is taken from this paper and there they mention that it is quadratic.

Well that is obviously incorrect as you have a square of a quadratic. What they do is that they write the nonconvex quartic model as a rank-constrained (thus non-convex) semidefinite program with a convex quadratic constraint.
