Thus, the length of a filament is not a model parameter.
Notation: • L is used both for the length of the trichome Nl and in the non-dimensionalization as 0 αν ζ . • I have never seen , ⋅⋅used to define an edge. It looks like an inner product. Is this standard? • In Equations (5)–(8), is there any difference between subscripts and superscripts? • It is confusing that b κ is a vector that is not simply related to b. I initially thought that κ was a new parameter. Similarly, it is odd that e is a vector and [e] is a matrix. Why not use the Levi–Civita tensor? • ˆ h looks like a unit vector parallel to h. Is there a reason that h only has a ˆ ⋅ in Equation (12)?
