SummaryIt is known that to every proper homogeneous Lorentz transformation there corresponds a unique proper complex rotation in a three-dimensional complex linear vector space, the elements of which are here called “rotors”. Equivalently one has a one-one correspondence between rotors and self- dual bi-vectors in space-time (w-space). Rotor calculus fully exploits this correspondence, just as spinor calculus exploits the correspondence between real world vectors and hermitian spinors; and its formal starting point is the definition of certain covariant connecting quantities τAkl which transform as vectors under transformations in rotor space (r-space) and as tensors of valence 2 under transformations in w-space.

The skew-circulant matrix has been used in solving ordinary differential equations. We prove that the set of skew-circulants with complex entries has an idempotent basis. On that basis, a skew-cyclic group of automorphisms and functional equations on the skew-circulant algebra is introduced. And different operators on linear vector space that are isomorphic to the algebra ofn×ncomplex skew-circulant matrices are displayed in this paper.

Paleochronic reversion is confirmed in Psophocarpus as a basic floral ground state. That state can expand to include dynamics T (g,,h) ) of axial expansion (AE) as a permutation (T X ) phase beginning as phyllotactic floral phylloid (T Phyld ) and/or axial decompression (T Axl ) manifest as linear elongation (T Long ) and/or rotation (T Rtn ) and/or latitudinal (TS Lat ) expansion. Organ regions present a continuum as a vector space LT Axl of floral axial transformation. A generative phase of meristem activity (T (Rz, SAM, Infl) ) can follow. Experiments with 49 phylloid and/or phyllome paleochronically reverted flowers presented varying degrees of phyllotactic permutation involving development of a pericladial stalk (PCL) and/or inter-bracts stem (IBS) and/or activated pedicel (PdcL) and/or gynophore (Gnf), Cupule-like (Gnf)/Cupl-Lk) elongation. A meristem generative function included rhizogeny as root site generation (RSG) at the calyx (Cl), PCL, bracts (Bt), IBS, PdcL and/or Gnf/Cupl-Lk regions manifest as eigenvector functions as RSG whose density of generation was associated with permutation of the ground state. A continuum of pedicel to calyx regions constitutes a subset [PdcL,Cl] of a linear vector space [Bt,Crpl]=T X → [PdcL,Crpl]=LT Axl whose extension is defined within the space: ∑ F PdcL + F Bt (1,,z) ± S IBS (1,,x) + F PCL (1,,w) + F Cl + F Gyncm ± S Gnf ± S Cupl-Lk = L T Axl . The vector space LT Axl transforms to a master vector field (F [c,..,d] ) of generated Euclidian eigenvectors so that: LT Axl → F [c,..,d]
