In the last few days, a Denial of Service attack was launched on universities in Israel, leading the administrators of the Israel Academic network to block access to it from the global internet. Consequently, websites such as ECCC have been accessible only from within the Israeli and European academic networks.
It seems that this blocking was just removed, and we hope it will not be put back in the future.
Needless to say, deciding on such blocking is not in our control, but we do apologize for this disruption of service.
In this paper we ask how much expansion one can retain with almost no edges beyond connectivity. Concretely, for graphs of average degree $2+\varepsilon$, what is the “Ramanujan bound’’—how does spectral expansion scale with $\varepsilon$? We compare five ultra–sparse graph models—including the configuration model, subdivision of regular expanders, and the ... more >>>
Interactive proofs of proximity (IPPs) are a relaxation of interactive proofs, analogous to property testing, in which soundness is required to hold only for inputs that are $\epsilon$-far from the property being verified, where $\epsilon>0$ is a proximity parameter. In such proof systems, the verifier has oracle access to the ... more >>>
A recent work of Goyal, Harsha, Kumar and Shankar gave nearly linear time algorithms for the list decoding of Folded Reed-Solomon codes (FRS) and univariate multiplicity codes up to list decoding capacity in their natural setting of parameters. A curious aspect of this work was that unlike most list decoding ... more >>>
