On the structure of complete G₂-solitons

In this work, we establish compactness theorems for complete gradient $G_2$-solitons under the assumptions of a lower bound on the scalar curvature and a broad growth condition on the potential function associated with the gradient vector field. After first proving Gromov-Hausdorff convergence for such sequences, we sharpen this result by deriving epsilon-regularity estimates. As a consequence, we obtain smooth convergence provided there is a uniform energy bound at half the dimension.
