We present a linear-time kernelization algorithm that transforms a given planar graph G with domination number γ(G) into a planar graph G of size O(γ(G)) with γ(G) = γ(G ). In addition, a minimum dominating set for G can be inferred from a minimum dominating set for G . In terms of parameterized algorithmics, this implies a linear-size problem kernel for the NP-hard Dominating Set problem on planar graphs, where the kernelization takes linear time. This improves on previous kernelizationdoi:10.1007/978-3-642-28050-4_16 fatcat:cvbceyuhu5crnjtfyrt5v7mstm
