In this paper, He’s variational iteration method (VIM) has been used to obtain solutions of the seventh-order Sawada-Kotera equation (sSK) and a Lax’s seventh order KdV equations(LsKdV).The numerical solutions are compared with the Adomian decomposition method(ADM) and the known analytical solutions.The work confirms the power of the VIM in reducing the size of calculations w.r.t. ADM. Some ill...

ASYMMETRY There exists a cross-linguistic asymmetry in availability of discourse items among adjunct clauses between because-clauses on one hand, and temporal clauses and if -clauses on the other (see examples (1) for English obviously , (2) for German ja and (3) for Japanese wa; see Hooper and Thompson 1973, Tenny 2002, Sawada and Larson 2004 among others for the same type of asymmetry with ot...

In this paper, the research object is $$(2+1)$$ -dimensional Korteweg–de Vries–Sawada–Kotera–Ramani (KdVSKR) equation. After adding new constraint, solutions which contain y-type molecules are obtained. The process of lump and before after collision studied by long-wave limit method, kinetic behavior analysis given. interactions between resonant soliton molecules, breather obtained combining ve...

Earota babai (Sawada, 1989), comb. nov. and Earota koreana (Paśnik, 2001), comb. nov. are transferred from the genera Pelioptera Kraatz, 1857 and Aloconota Thomson, 1858, respectively. Earota babai is recorded from the Korean Peninsula for the first time and E. koreana is a new addition to South Korea. Redescriptions, habitus photographs, illustrations of diagnostic characters of these two spec...

In this paper, the Sawada-Kotera equation is solved by using the Adomian’s decomposition method, modified Adomian’s decomposition method, variational iteration method, modified variational iteration method, homotopy perturbation method, modified homotopy perturbation method and homotopy analysis method. The approximate solution of this equation is calculated in the form of series which its comp...
