This paper is concerned with the fractional fifth‐order KdV types of equations, the complete
group classification is performed on the general fractional fifth‐order partial differential …

Invariant solutions for the modified Khokhlov–Zabolotskaya–Kuznetsov (KZK) equation are
obtained by using classical Lie symmetries. The complete set of local point symmetries is …

In this paper, we address a one‐dimensional quasi‐linear hyperbolic system of equations
describing blood flow through compliant axi‐symmetric vessels. From the symmetry …

In this paper, the systems of carbon nanotubes (CNTs) conveying fluid are considered by the
combination of Lie symmetry analysis and the dynamical system method. All of the …

In this paper, the combination of Lie symmetry analysis and the dynamical system method is
performed on the mixed second-order sine-Gordon equation, all of the geometric vector …

This paper is concerned with the variable-coefficient nonlinear evolution equations, which
include the cylindrical KdV types of equations. By the combination of Painlevé analysis and …

Using the Lax pair, nonlocal symmetries of the coupled Hirota equations are obtained. By
introducing an appropriate auxiliary dependent variable, the nonlocal symmetries are …

Errors in the mathematical derivations have been identified that are found to be unfixable.
Such errors have rendered the main results in the paper erroneous. The authors apologise …

In this paper, we investigate the time-fractional generalized thin film equation (TFGTFE) with
two arbitrary functions and perform the group classification with respect to these arbitrary …

This paper investigates the generalized fractional porous medium equations (GFPMEs)
which are the generalizations of the dual porous medium equation with integer order …
