abstract = {The $a$-number is an invariant of the isomorphism class of the p-torsion group scheme. In this paper, we compute a closed formula for the $a$-number of $y^q + y = x^{frac{q+1}{3}}$ and $sum_{t=1}^{s} y^{q/3^t}= x^{q+1}$ with $q = 3^s$ over the finite field $mathbb{F}_{q^2}$ using the action of the Cartier operator on $H^0(mathcal{C},Omega^1)$.},
