abstract

  • We consider the task of testing properties of Boolean functions that are invariant under linear transformations of the Boolean cube. Previous work in property testing, including the linearity test and the test for Reed-Muller codes, has mostly focused on such tasks for linear properties. The one exception is a test due to Green for "triangle freeness": A function f: F 2n → F2 satisfies this property if f(x),f(y),f(x + y) do not all equal 1, for any pair x,y ∈ F 2n. Here we extend this test to a more systematic study of testing for linear-invariant nonlinear properties. We consider properties that are described by a single forbidden pattern (and its linear transformations), i.e., a property is given by k points v1,⋯,vk ∈ F2k and f: F2n → F 2 satisfies the property that if for all linear maps L: F 2k → F2n it is the case that f(L(v1)),⋯,f(L(vk)) do not all equal 1. We show that this property is testable if the underlying matroid specified by v 1,⋯,vk is a graphic matroid. This extends Green's result to an infinite class of new properties. Our techniques extend those of Green and in particular we establish a link between the notion of "1-complexity linear systems" of Green and Tao, and graphic matroids, to derive the results. © A.
