Query: Symbolic Powers of Cover Ideals of Graphs and Koszul Property   We show that attaching a whisker (or a pendant) at the vertices of a cycle
cover of a graph results in a new graph with the following property: all
symbolic powers of its cover ideal are Koszul or, equivalently, componentwise
linear. This extends previous work where the whiskers were added to all
vertices or to the vertices of a vertex cover of the graph.
