  Abstract: Fellows, Guo, Moser and Niedermeier 14 proved a generalization of Nemhauser and Trotter's theorem, which applies to d-Bounded-Degree Vertex Deletion (to delete k vertices of the input graph to make the maximum degree of it źd) and gives a linear-vertex kernel for d = 0 and 1, and a superlinear-vertex kernel for each d ź 2 for the problem parameterized by k. It is still left as an open problem whether this parameterized problem admits a linear-vertex kernel for each d ź 3 . In this paper, we refine the generalized Nemhauser and Trotter's theorem and give a linear-vertex kernel for each d ź 0 . We prove a generalization of Nemhauser and Trotter's local optimization theorem.We obtain the first linear kernel for d-Bounded-Degree Vertex Deletion parameterized by the deletion size k for each fixed d ź 3 .We obtain the first linear kernel for d-Star Packing parameterized by the packing size k for each fixed d ź 3 .
