On exponential Yang-Mills fields and $p$-Yang-Mills fields

Abstract

We introduce \emph{normalized exponential Yang-Mills energy functional} ${\mathcal{Y}\mathcal{M}}_e^0$, stress-energy tensor $S_{e,{\mathcal{Y}\mathcal{M}}^0}$ associated with the normalized \emph{exponential Yang-Mills energy functional} ${\mathcal{Y}\mathcal{M}}_e^0$, $e$-conservation law. We also introduce the notion of the {\it $e$-degree} $d_e$ which connects two separate parts in the associated normalize exponential stress-energy tensor $S_{e,{\mathcal{Y}\mathcal{M}}^0}$ (cf. (3.10) and (4.15)), derive monotonicity formula for exponential Yang-Mills fields, and prove a vanishing theorem for exponential Yang-Mills fields. These monotonicity formula and vanishing theorem for exponential Yang-Mills fields augment and extend monotonicity formula and vanishing theorem for $F$-Yang-Mills fields in [DW] and [W11, 9.2]. We also discuss an average principle (cf. Proposition 8.1), isoperimetric and Sobolev inequalities, convexity and Jensen's inequality, $p$-Yang-Mills fields, an extrinsic average variational method in the calculus of variation (cf.[W1, W3]) and ${\Phi }_{(3)}$-harmonic maps, from varied, coupled, generalized viewpoints and perspectives (cf. Theorems 6.1, 7.1, 9.1, 9.2, 10.1,10.2, 11.13, 11.14, 11.15)).
