Abstract

In this paper we study, both numerically and analytically, the asymptotic behavior of the principal eigenfunction of (1.1), normalized by (1.2), as s↑+∞. Based on the numerical computations of this paper, we can prove that, under condition (Hm) below, φs approximates 1 and φs′ approximates 0, uniformly in [−1,1], as s↑+∞. As a byproduct of this result, we can derive the asymptotic behavior of the principal eigenvalue in a one-dimensional situation not previously covered by Chen and Lou (2008) and Peng and Zhou (2018), as we are working under minimal regularity assumptions on m(x). A recent result of Bai et al. (2025) shows that the principal eigenvalue might oscillate as s↑+∞ if m(x) is highly oscillatory. Thus, the lack of regularity of m(x) might severely affect the behavior of (λs,φs) as s↑+∞.
