A conjecture about the entropy of matrix vector products
Your "new part" looks like the core of the problem but I have to admit, looks no easier to me. It will be great if you (or anyone) has any ideas about this new formulation. |

What is $\lim_{n\to\infty} \displaystyle \sum_{k=0}^{\lfloor n/2 \rfloor} \binom{n}{2k}\left(4^{-k}\binom{2k}{k}\right)^{\frac{2n}{\log_2{n}}}\,?$
Can I ask my question again in that case? Is the OP right that convergence depends on the constant in the exponent? |

Is the OP right that convergence depends on the constant in the exponent? I can't immediately tell from your answer. |

Smallest non-zero eigenvalue of a (0,1) matrix
There is nothing better than an explicit construction. Thank you. Although it would be great if I could accept the upper and lower bounds answers together. |

Expected maximum inner product
Thank you. Is there a matching lower bound which tells me that it is exponentially unlikely to take values smaller than anything just a tiny bit smaller than $\sqrt{m}$ too? |

Probability a random Toeplitz matrix is singular
@Suvrit Can you give any more details? |
