This work discusses the existence of the limit as p goes to 1 of the nontrivial solutions to the one-dimensional problem:
$$\begin{aligned} {\left\{ \begin{array}{ll} -\left( |u_x|^{p-2} u_x\right) _x = \lambda |{u}|^{{p}-2}{u} -|{u}|^{{q}-2}{u}&{} \quad 0< x < 1\\ u(0)=u(1)=0, &{} \end{array}\right. } \end{aligned}$$where \(\lambda \) is a positive parameter and the exponents p, q satisfy \(1< p < q\). We prove that solutions do converge to a limit function, which solves in a proper sense a Dirichlet problem involving the 1-Laplacian operator.

这项工作讨论了当p变为一维问题的非平凡解中的1时极限的存在:
$$ \ begin {aligned} {\ left \ {\ begin {array} {ll}-\ left(| u_x | ^ {p-2} u_x \ right)_x = \ lambda | {u} | ^ {{p } -2} {u}-| {u} | ^ {{q} -2} {u}&{} \ quad 0 <x <1 \\ u(0)= u(1)= 0,&{ } \ end {array} \ right。} \ end {aligned} $$其中\(\ lambda \)是一个正参数,指数p, q满足\(1 <p <q \)。我们证明了解确实收敛到极限函数,该极限函数在适当的意义上解决了涉及1-Laplacian算子的Dirichlet问题。
