The fundamental particle photon and the basic idea of nonlinearity receive attention here. The powerful notion of photon-like objects in nature is introduced and discussed briefly in the paper. The nonlinear connection view on the Frobenius integrability theory on manifolds is considered as a useful frame in which an appropriate description of photon-like objects can be successfully developed and investigated.
The specific sections are: The notion of photon-like objects (PhLO); Nonlinear connections; Back to PhLO; Translational-rotational consistency. There are two figures illustrating certain theoretical examples. Presented are also 3 propositions with proof and discussion. The intricate and interesting relationships between mathematics and physics are spelt out in a very subtle, useful manner. This invites more intensive efforts for establishing further results on the concepts of nonlinearity and the beautiful photon.
