Abstract: | Single or/and multipeak solitons in plasma under relativistic electromagnetic field are reviewed. The incident electromagnetic
field is allowed to have a zero or/and nonzero initial constant amplitude. Some interesting numerical results are obtained
that include a high-number multipeak laser pulse and single or/and low-number multipeak plasma wake structures. It is also
shown that there exists a combination of soliton and oscillation waves for plasma wake field. Also, the electron density exhibits
multi-caviton structure or the combination of caviton and oscillation. A complete eigenvalue spectrum of parameters is given
wherein some higher peak numbers of multipeak electromagnetic solitons in the plasma are included. Moreover, some interesting
scaling laws are presented for field energy via numerical approaches. Some implications of results are discussed.
