  • Abstract
    The authors prove that the symmetric difference of a ⩽P k-parity-hard set for E and a subexponential time computable set is still ⩽Pk-parity-hard for E. This remains true for a ⩽Pm-hard set for E since 1-parity reduction is many-one reduction. In addition, it is shown that it is not the case with respect to some other types of reductions. The authors introduce and study the notions of E-complete and E-hard kernels
