Binary Codes with Resilience Beyond 1/4 via InteractionAdvances in the Theory of Error-Correcting Codes2024-04-08
Constructs two-way binary codes that achieve resilience strictly >1/4 at constant rate with Bob sending one short reply, using a three-round non-adaptive…

Noisy Radio Network Lower Bounds Via Noiseless Beeping Lower BoundsITCS 20232023-01-10
Proves that noisy-CAS vs CAS can incur the worst-case slowdown Θ(log n): any adaptive protocol that uses √n rounds on CAS yields an equivalent beeping (OR)…

Computation Over the Noisy Broadcast Channel with Malicious PartiesITCS 20212021-01-06
Shows a protocol that computes bit‑exchange over a noisy broadcast channel tolerating up to half malicious parties while cutting per‑player communication from…

Tutorial on List Decodable Coding Schemes and Interactive Communication in Networks (Part 1 of 2)Information Theory in Complexity Theory and Combinatorics 20152015-04-24
Shows a protocol that uses list decoding/list recovery to solve pointer‑jumping: given Alice and Bob’s layered edge sets the protocol outputs a small list of…

Circuits of Bounded DepthAlgorithms and Complexity in Algebraic Geometry Boot Camp 20142014-09-02
Claims an exponential lower bound: any depth-d arithmetic circuit computing the n×n determinant needs size at least exp(Ω(n^{1/d})), proven by exhibiting…
