Two-dimensional solutions of a mean field equation on flat tori

Multiple Axially Asymmetric Solutions to a Mean Field Equation on $\mathbb{S}^{2}$

“…In order to overcome this obstacle, we follow the method from [2] by searching for spaces with some symmetry. Multiple two-dimensional solutions of mean field equation on flat tori bifurcating from trivial solution can be seen in [10].…”
