In this paper we present a closed formula for the values of the $q$-analog of Kostant's partition function for the Lie algebra $\mathfrak{sp}_4(\mathbb{C})$ and use this result to give a simple formula for the $q$-multiplicity of a weight in the representations of the Lie algebra $\mathfrak{sp}_4(\mathbb{C})$. This generalizes the 2012 work of Refaghat and Shahryari that presented a closed formula for weight multiplicities in representations of the Lie algebra $\mathfrak{sp}_4(\mathbb{C})$.
Keywords: Sympletic Lie algebra, $q$-analog of Kostant partition function, weight multiplicity, weight $q$-multiplicity.
Mots-clés : Kostant partition functions
