This article.give. a ge.e.al mode. using spe.ific pe.iodic spe.ial functions, that is, de.e.e.ate.e.liptic We.e.strass P functions compose. with the.Lambe.tW function, whose.pre.e.ce.in the.gove.ning e.uations through the.forcing te.ms simplify the.pe.iodic Navie. Stoke. e.uations (PNS) at the.ce.te.s of arbitrary r balls of the.3-Torus. The.continuity e.uation is satisfie. toge.he. with spatially pe.iodic boundary conditions. The.yicompone.t forcing te.ms consist of a function F as part of its e.pre.sion that is arbitrarily small in an r ball whe.e.it is associate. with a singular forcing e.pre.sion both for inviscid and viscous case.. As a re.ult, a significant simplification occurs with a v3(vifor all ve.ocity compone.ts) only gove.ning PDe.re.ulting. The.e.te.sion of thre. re.tricte. subspace. in e.ch of the.principal dire.tions in the.Carte.ian plane.is shown as the.Carte.ian product ℋ=Jx,t×Jy,t×Jz,t.
