Matrix concentration inequalities, intimately connected to the Non-Commutative Khintchine inequality, have been an important tool in both applied and pure mathematics. We study …
We prove that for every odd $ q\geq 3$, any $ q $-query binary, possibly non-linear locally decodable code ($ q $-LDC) $ E:\{\pm1\}^ k\rightarrow\{\pm1\}^ n $ must satisfy $ k\leq\tilde …
We give improved lower bounds for binary $3 $-query locally correctable codes (3-LCCs) $ C\colon\{0, 1\}^ k\rightarrow\{0, 1\}^ n $. Specifically, we prove:(1) If $ C $ is a linear design 3 …
In this thesis, we present a new method to solve algorithmic and combinatorial problems by (1) reducing them to bounding the maximum, over 𝑥∈{− 1, 1} 𝑛, of homogeneous degree-𝑞 …
