Lojasiewicz--Simon gradient inequalities for the harmonic map energy function

We apply our abstract gradient inequalities developed by the authors in arXiv:1510.03817 to prove Lojasiewicz–Simon gradient inequalities for the harmonic map energy function using Sobolev spaces which impose minimal regularity requirements on maps between closed, Riemannian manifolds. Our Lojasiewicz–Simon gradient inequalities for the harmonic map energy function generalize those of Kwon (2002), Liu and Yang (2010), Simon (1983, 1985), and Topping (1997).
