Analysis & Applications Seminar Speaker: Erik Lundberg, Professor, Department of Mathematics & Statistics, Florida Atlantic University Title: Erdős Problem #1039 on the inradius of polynomial lemniscates (Part II) Abstract: This talk will take a look at Erdos Problem labeled #1039 on the Erdos Problems Forum https://www.erdosproblems.com/1039 Erdős, Herzog, and Piranian asked in 1958 whether every monic polynomial p of degree n with all zeros in the unit disk has a disk of radius at least c/n on which its modulus is everywhere less than 1, where c > 0 is an absolute constant. In other words, the problem concerns the inradius (radius of the largest inscribed disk) of the polynomial lemniscate {z: |p(z)| \leq 1} and whether it admits a lower bound of order 1/n. This problem was recently resolved using AI. I’ll discuss the problem, previous progress, and my impression of the AI solution (and how it compares to other AI assisted preprints that have crossed my path). |

Speaker: Yuhao Liu, Department of Mathematics & Statistics, Florida Atlantic University Title: Gröbner Basis and Relinearization Algorithm for Ring-LWE +Zoom (click here) Abstract: \textbf{Abstract.} We analyze the Gr\"obner basis attack on the Arora--Ge system \cite{AroraG11} arising from Ring-LWE samples over \[ \mathcal{R}_q = \mathbb{F}_q[X]/(X^n+1), \] with $n$ a power of two and errors bounded by $b$. We show that, with high probability over the sampled public polynomials, the highest-degree components of the resulting polynomial system span the full space of forms of degree $k$ (where $k = 2b + 1$), so that the system is semi-regular with degree of regularity $k$. Furthermore, we quantify the failure probability through a factorization of the degree-$k$ Macaulay determinant into $n$ blocks indexed by the frequencies of a negacyclic Fourier transform and permuted by Frobenius. We further show that this structure block-diagonalizes the dominant part of the linearized system and reduces the cost of the attack from \[ \Theta\!\left(n^{k\omega}\right) \] to \[ \Theta\!\left(n^{(k-1)\omega+1}\right) \] arithmetic operations in the splitting field of $X^n+1$, a saving of a factor $n^{\omega-1}$ over the corresponding unstructured computation. For ternary errors, this yields the complexity reduction \[ \Theta(n^{9}) \rightarrow \Theta(n^{7}) \] for $\omega = 3$.

AMC 10/12B The Mathematical Association of America hosts the annual AMC contests for middle and high school students. We began the AMC10-12 Contests in as early as 2007. Its purpose is to spur interest in mathematics and develop talent through the excitement of friendly competition at problem-solving in a timed format. The event will be held in Phil Smith Hall, BU 109. |
