1. Introduction
The lump soliton solutions have been commonly used in many natural sciences such as chemistry, biology, etc. In particular, in almost all branches of physics, engineering such as fluid dynamics, plasma physics, optics, etc [1–3] the lump soliton solutions play an important role. While some researchers used numerical simulation or analytical methods to investigate the performance of such structures, further study of the theoretical analysis of such systems is required [4–6]. Rogue waves (RW) are expansive and instinctive ocean waves that have drawn growing focus on both theoretical and experimental observations [7]. The RW for nonlinear Schrödinger equation in its simplest form has been proposed in [8]. It can be seen that there are huge wave phenomena in different fields such as plasmas, nonlinear optics, Bose–Einstein condensates, biophysics and even finance. [9–11]. In terms of a new combination of variable functions using the Hirota bilinear model, some researchers are working out some new solutions from the lump solution family and some groups of interaction solutions. We are reviewing some literature on the phenomena of lump solutions and their interaction. To this aim, there have been series of presentation of lump solutions from different perspectives, for instant, Zakharov [12], pump wave solution [13], lump solution through Hirota bilinear method [3, 14–16]. Through important properties of lump solutions it can be understood that amplitudes, shapes, speeds of solitons will be preserved after collision with another soliton and this is the elastic property of collision. Moreover, interaction between rouge wave and kink solitary wave solution have been established in [17]. Several other types of solution can also be found in [18–22].

In this study, we utilise the Hirota bilinear approach to construct some novel lump-type and interaction solutions for the (3+1)-dimensional soliton equation [18] given by1 ) was first introduced in [23] in the study of the algebraic-geometrical solutions. The physical behaviour of the obtained solutions are also depicted in figures 1–5 in order to shed more light on the presented solutions.
$ \begin{eqnarray}3{\chi }_{{xz}}-{\left(2{\chi }_{t}+{\chi }_{{xxx}}-2\chi {\chi }_{x}\right)}_{y}+2{\left({\chi }_{x}{\partial }_{x}^{-1}{\chi }_{y}\right)}_{x}=0.\end{eqnarray}$
The (3+1)-dimensional integrable equation (2. Lump and its interaction solutions
In part, we present the new lump and its interaction solutions to the (3+1)-dimensional soliton equation given in equation (1 ).

We first transform equation (1 ) into its bilinear form.
Set2 ) into (1 ), yields4 ) to the following (2+1)-dimensional soliton equation:6 ) into (5 ), gives the following bilinear form:
$ \begin{eqnarray}\chi ={{\rm{\Theta }}}_{x}.\end{eqnarray}$
Substituting equation ( $ \begin{eqnarray}\begin{array}{l}2{{\rm{\Theta }}}_{{xyt}}+{{\rm{\Theta }}}_{{xxxxy}}-4{{\rm{\Theta }}}_{{xy}}{{\rm{\Theta }}}_{{xx}}-3{{\rm{\Theta }}}_{{xxz}}\\ \quad -\,2{{\rm{\Theta }}}_{x}{{\rm{\Theta }}}_{{xxy}}-2{{\rm{\Theta }}}_{y}{{\rm{\Theta }}}_{{xxx}}=0.\end{array}\end{eqnarray}$
Setting $ \begin{eqnarray}{\rm{\Theta }}(x,y,z,t)={\rm{\Theta }}(\xi ),\ \ \ \xi =x+\sigma y,\end{eqnarray}$
reduces equation ( $ \begin{eqnarray}2\sigma {{\rm{\Theta }}}_{\xi \xi t}+\sigma {{\rm{\Theta }}}_{\xi \xi \xi \xi \xi }-4\sigma {{\rm{\Theta }}}_{\xi \xi }^{2}-3{{\rm{\Theta }}}_{\xi \xi z}-4\sigma {{\rm{\Theta }}}_{\xi }{{\rm{\Theta }}}_{\xi \xi \xi }=0.\end{eqnarray}$
Consider the Cole–Hopf transformation $ \begin{eqnarray}{\rm{\Theta }}(\xi ,z,t)=-3\displaystyle \frac{\partial \left(\mathrm{ln}f(\xi ,z,t\right)}{\partial \xi }.\end{eqnarray}$
Substituting equation ( $ \begin{eqnarray}\begin{array}{l}3\sigma {f}_{\xi \xi }^{2}-2\sigma {f}_{t}{f}_{\xi }+f\left(2\sigma {f}_{\xi t}-3{f}_{\xi z}\right)\\ \quad +\,{f}_{\xi }\left(3{f}_{z}-4\sigma {f}_{\xi \xi \xi }\right)+\sigma {{ff}}_{\xi \xi \xi \xi }=0.\end{array}\end{eqnarray}$
2.1. Lump solution
In this section, we report the lump solutions to equation (1 ).
Consider the positive quadratic solutions to the bilinear equation (7 )8 ) into (7 ) gives a polynomial in powers of ξ, z and t. Collecting the coefficients of the same power, and equating each summation to zero, produces an algebraic system of equations. We solve the system of equations to obtained the values of the parameters involved. Substituting the values of the parameters into equation (6 ) and then into equation (2 ), gives the following lump solutions to equation (1 ):
$ \begin{eqnarray}\begin{array}{l}g={b}_{1}\xi +{b}_{2}z+{b}_{3}t+{b}_{4},\ \ h={b}_{5}\xi +{b}_{6}z\\ \qquad +\,{b}_{7}t+{b}_{8},\ \ f={g}^{2}+{h}^{2}+{b}_{9}.\end{array}\end{eqnarray}$

3. Conclusion
Via the Hirota bilinear approach and symbolic computation, the (3+1)-dimensional soliton equation is investigated in this study. Various new lump, lump-kink, breather wave, lump periodic, and some other new interaction solutions are successfully constructed. Using the Mathematica 12 package, all the acquired solutions are verified by inserting them into the original equation. The physical characteristics of the solution were graphically depicted to shed more light on the obtained results under the choice of suitable values of the parameters. The results obtained may be useful in understanding the basic nonlinear scenarios in fluid dynamics as well as the dynamics of computational physics and engineering sciences in nonlinear fields of higher dimensional motion.
