Abstract
We consider the following graph modification problem. Let the input consist of a graph G=(V,E) , a weight function w:V∪E→N , a cost function c:V∪E→N and a degree function δ:V→N0 , together with three integers kv , ke and C. The question is whether we can delete a set of vertices of total weight at most kv and a set of edges of total weight at most ke so that the total cost of the deleted elements is at most C and every non-deleted vertex v has degree δ(v) in the resulting graph G′ . We also consider the variant in which G′ must be connected. Both problems are known to be NP -complete and W[1] -hard when parameterized by kv+ke . We prove that, when restricted to planar graphs, they stay NP -complete but have polynomial kernels when parameterized by kv+ke .
