where F is a path on X Poincar~-dual to the cohomology class of dh3, h~ is a function on obtained by integrating dh~, and r/12 is a 1-form on X satisfying drl12=dh,Adh2 (and orthogonal to all closed 1-forms); second, as a volume modZ: namely by (1.2), we can integrate the dh~ on X to obtain hi: X---~R/Z which are harmonic. Then h=(h~, h 2, h~): X--->R3/Z3=T 3, and it follows easily from (1.1) that h(X), regarded as a singular 2-cycle, bounds a singular 3-chain c3 (unique mod integral 3-cycles); we can then take the volume of c3 (mod Z) to define l(dh~, dh2, dh3): we call this a "harmonic vo lume" .
