Counting YangMills Dyons with Index Theorems
Stern, Mark A; Yi, P (Phys.Rev. D, 20170601)We count the supersymmetric bound states of many distinct BPS monopoles in N=4 YangMills theories and in pure N=2 YangMills theories. The novelty here is that we work in generic Coulombic vacua where more than one adjoint ... 
Invariance Theorems for Supersymmetric YangMills Theories
Sethi, S; Stern, Mark A (Adv.Theor.Math.Phys., 20170601)We consider quantum mechanical YangMills theories with eight supercharges and a $Spin(5) \times SU(2)_R$ flavor symmetry. We show that all normalizable ground states in these gauge theories are invariant under this flavor ... 
Monopole and dyon bound states in N = 2 supersymmetric YangMills theories
Sethi, S; Stern, Mark A; Zaslow, E (Nuclear Physics, Section B, 19951225)We study the existence of monopole bound states saturating the BPS bound in N = 2 supersymmetric YangMills theories. We describe how the existence of such bound states relates to the topology of index bundles over the moduli ... 
Nonlinear Harmonic Forms and an Indefinite Bochner Formula
Stern, Mark A (20170601)We introduce the study of nonlinear harmonic forms. These are forms which minimize the $L_2$ energy in a cohomology class subject to a nonlinear constraint. In this note, we include only motivations and the most basic existence ... 
Price Inequalities and Betti Number Growth on Manifolds without Conjugate Points
Cerbo, LFD; Stern, Mark A (20170601)We derive Price inequalities for harmonic forms on manifolds without conjugate points and with a negative Ricci upper bound. The techniques employed in the proof work particularly well for manifolds of nonpositive sectional ...
