- Derived formulas for multiplicity based on graph edges.
- Enhanced understanding of algebraic invariants in graph theory.

## Abstract

In this paper, we compute the regularity and Hilbert series of symbolic powers of the cover ideal of a graph $G$ when $G$ is either a crown graph or a complete multipartite graph. We also compute the multiplicity of symbolic powers of cover ideals in terms of the number of edges.
