The review summarises recent theoretical achievements and observational manifestations
of a new, recently discovered type of nonlinear oscillations in multi-component plasmas …

A new class of nonlinear waves in plasma—supernonlinear waves (SNWs) characterized by
the nontrivial topology of their phase portraits—has been revealed. The topological …

The nonlinear propagation of amplitude-modulated electrostatic wavepackets in an electron–
positron–ion (e–p–i) plasma is considered, by employing a two-fluid plasma model …

Small amplitude propagation and quasielastic head-on collision of ion-acoustic solitary
waves (IASWs) are investigated in a degenerate Thomas–Fermi electron-positron-ion …

Linear and nonlinear coupled kinetic Alfven acoustic (CKAA) waves in low-β electron–
positron–ion (epi) plasmas are investigated in this paper, and the main focus is on …

Large-amplitude ion-acoustic solitary wave (IASW) propagation and matching criteria of
existence of such waves are investigated in a degenerate dense electron-positron-ion …

Propagation of arbitrary-amplitude ion-waves is investigated in an extremely degenerate
electron-positron-ion plasma with relativistic electrons/positrons and dynamic cold ions …

The existence of both subsonic (M< 1) and supersonic (M> 1) compressive (N> 1) solitons
within a three-dimensional magnetized plasma model featuring thermal ions and electrons …

Using the extended Poincaré–Lighthill–Kuo reductive perturbation method to study the small-
amplitude ion acoustic solitary wave dynamics (propagation and interaction), it is shown that …

Of the nonlinear excitations, ion-acoustic solitary waves (IASWs) are of the most important
and wellunderstood characteristics of plasma environments. Theoretical studies of main …
