“…Therefore, the solution of NPDEs naturally becomes an important part of nonlinear theory. And, for the time being, many different kinds of the powerful approaches have been derived to handle the NPDEs, such as the extended F-expansion method (Bhrawy et al , 2012; Pandir and Turhan, 2021; Abdou, 2007; Rabie and Ahmed, 2022), Bäcklund transformation (Ma et al , 2021; Yin et al , 2021a, 2021b; Han and Bao, 2021; Du et al , 2018), variational technique (Wang, 2022; Wang, 2023), exp-function approach (Raza and Javid, 2019; Mohyud‐Din et al , 2012; He and Wu, 2006; Wu and He, 2008), general integral method (Shang, 2010; Zayed et al , 2022), trial equation method (Afzal et al , 2019; Raza and Javid, 2019) and so on (Seadawy et al , 2018; Wang et al , 2023a, 2023b, 2023c; Raza et al , 2019; Wang and Liu, 2022; Rezazadeh et al , 2020; Sağlam Özkan et al , 2021; Asjad et al , 2022; Rehman et al , 2022; Seadawy et al , 2021; Rizvi et al , 2020; Wang et al , 2023a, 2023b, 2023c; Kaplan et al , 2016; Hosseini and Ayati, 2016). The purpose of this study is to construct the some novel exact solutions of the new (3 + 1)-dimensional integrable fourth-order nonlinear equation (IFNE), which reads as (Wazwaz, 2021): where Ξ = Ξ ( x , y , z , t ), which is usually used to describe the both right and left travelling waves which is like the Boussinesq equation.…”
