semidirect

Adjective

semidirect (not comparable)

1. Neither unqualifiedly direct nor unqualifiedly indirect.
   • In the next step, the giant dipole state may deexcite by the emission of γ-rays. This reaction is called "semidirect". It turns out that direct and semidirect reactions play a dominating role at neutron energies higher than about 5 MeV.1984, I. Berqvist, Chapter II: Fast Neutron Radiative Capture, B. J. Allen, I.

   • In response to the supplier's request for improving the semidirect operations (parts supply and line management operations) at the final assembly processes and reducing labor requirements for semidirect operations, JMAC began its assessment of the situation by researching and analyzing in detail...2003, Toshiki Naruse, Equalized & Synchronized Production: The High-Mix Manufacturing System that Moves Beyond JIT, page 8
2. That has the nature of, or has a nature that derives from or is analogous to, a semidirect product.
   • It follows from 2° that σ induces the action homomorphism θ = σπ₁, which we call semidirect. We say that σ is a homomorphic transformation of (A, U).
   • If θ is the semidirect action homomorphism, then it follows from 1° that the θ-module is the semidirect sum ^𝔇 of (A^× U^×) and (B, V).1971, Transactions of the Moscow Mathematical Society, page 261
