Gs dvd property

GuruswamiSudan.gs_dvd_property

Plain-language statement

Divisibility via the rate-corrected GS system. Uses gs_degree_bound (ρ=k/n) and gs_johnson instead of the conservative proximity_gap versions.

Gs sufficient multiplicity bound

GuruswamiSudan.gs_sufficient_multiplicity_bound

Plain-language statement

The degree bound with ρ = k/n is strictly less than m times the number of agreement points, provided the distance is within the rate-corrected Johnson radius gs_johnson.
