“…The purpose of this paper is to establish the existence of at least one positive radial increasing weak solution of the problem (1.1) in the first order Sobolev space with variable exponent. We point out the authors have proved the existence of solutions to the problems in some special cases of f and g for a(x, t) = |t| p(x)−2 t on the Heisenberg groups (see [15,[19][20][21][22][23][24] for more details).…”
We make use of variational methods to prove the existence of at least one positive radial increasing weak solution to a Leray–Lions type problem under Steklov boundary conditions.

“…We point out that our approaches also fit with slightly different versions of the problem ( P ), e.g., with p(x)-Laplacian operator or the Heisenberg p-Laplacian operator or even the weighted Heisenberg p-Laplacian operator on the left hand side. Interested reader can see more details in [18,19,[26][27][28][29][30][31][32] and the references therein.…”

“…Also, He et al [5] proved the decay and the finite time blow-up for weak solutions of the equation, by using the potential well technique and concave technique. Recently many other authors investigated higher-order hyperbolic and parabolic type equation [2,3,6,[11][12][13][14][15]. Ishige et al [6] studied the Cauchy problem for nonlinear higher-order heat equation as follows…”
This paper deals with the initial boundary value problem for a higher-order parabolic equation with logarithmic source termBy employing the potential wells technique we show the global existence of the weak solution. Also, we obtain the exponential decay for the weak solutions.
