Each mentioned pair puts together a class of ˇ°waveˇ± elements and a class of ˇ°wave-wave regular interactionˇ± elements. A classifying parallel is finally constructed between the two analogous pairs of classes -- making evidence of some consonances and, concurrently, of some nontrivial contrasts. %K geometrical approach %K two-dimensional solutions %K quantifiable ˇ°amountˇ± of genuine nonlinearity %K regular interaction vs. irregular interaction: heuristic details %U http://bulletin.incas.ro/files/dinu_liviu__i_dinu_v3_iss_4_full.pdf
