In this paper, we study the initial boundary value problem of the pseudo-parabolic equation with a conformable derivative. We focus on investigating the existence of the global solution and examining the derivative's regularity. In addition, we contributed two interesting results. Firstly, we proved the convergence of the mild solution of the pseudo-parabolic equation to the solution of the parabolic equation. Secondly, we examine the convergence of solution when the order of the derivative of the fractional operator approaches $ 1^- $. Our main techniques used in this paper are Banach fixed point theorem and Sobolev embedding. We also apply different techniques to evaluate the convergence of generalized integrals encountered.
在本文中,我们研究了具有共形导数的拟抛物方程的初边值问题。我们着重研究全局解的存在性并考察导数的正则性。此外,我们得到了两个有趣的结果。首先,我们证明了拟抛物方程的温和解向抛物方程解的收敛性。其次,我们考察了分数阶算子导数的阶数趋于$1^-$时解的收敛性。本文使用的主要技术是巴拿赫不动点定理和索伯列夫嵌入。我们还应用了不同的技术来评估所遇到的广义积分的收敛性。
