Fig. 11
Two overlapping flows t 1 and t 2 transformed by a split into \(t^{\prime }_{1}=(v,\{e'_{1}\ldots e'_{2n}\})\), \(t^{\prime }_{2}=(v,\{\epsilon '_{1}\ldots \epsilon '_{2\nu }\})\) and \(t^{\prime }_{3}=(v,\{e''_{1}\ldots e''_{4}\})\). In parentheses are indicated the weightings required to maintain equality of conjugate flow, namely, \(\alpha \hat w(t_{1}) + \beta \hat w(t_{2}) = \alpha \hat w(t'_{1}) + \beta \hat w(t'_{2}) + (\alpha + \beta) \hat w(t'_{3})\)
