The space B 0 i = Imm 0 (S 1 , R 2)/ Diff(S 1) of all immersions of rotation degree 0 in the plane modulo reparametrizations has homotopy groups π 1 (B 0 i) = Z, π 2 (B 0 i) = Z, and π k (B 0 i) = 0 for k ≥ 3.

We formulate a stochastic gauge fixing method to study the gauge dependence of the Abelian projection. We consider a gauge which interpolates between the maximal Abelian gauge and no gauge fixing. We have found that Abelian dominance for the heavy quark potential holds even in a gauge which is far from maximally Abelian one. The heavy quark potentials from… (More)

Seasonal characteristics of surface water fulvic acids (FAs) isolated from Japanese clear-water lakes were investigated. Qualitative changes in Lake Biwa and Lake Tankai FAs were determined and compared. Although the relative molecular weights determined by high-performance size-exclusion chromatography did not change remarkably, the elemental compositions,… (More)
