AI 中文摘要
本文在广义相对论框架下提出了一种由广义幽灵暗能量（GGDE）源构造的虫洞解。首先简要回顾GGDE并给出必要的数学框架；采用马尔可夫链蒙特卡罗（MCMC）技术，结合CC+BAO、Pantheon+及其组合数据集约束模型的自由参数；进一步使用赤池信息准则（AIC）和贝叶斯信息准则（BIC）对模型性能进行统计评估，确定其可接受程度。接着详细解释虫洞几何的基本原理及薄壳形式主义，之后给出对应三种不同红移函数选择的三种虫洞解，通过图形研究其各类几何性质与能量条件；最后通过研究相关有效势，从解析和图形两方面检验这些薄壳结构的稳定性。
英文摘要
This article presents a wormhole solution constructed from a generalized ghost dark energy (GGDE) source in general relativity. At first, a brief review of GGDE is presented along with the necessary mathematical frameworks. We employed the Markov Chain Monte Carlo (MCMC) technique to constrain the free parameters of the model using the CC+BAO, $Pantheon^+$, and their combined datasets. Furthermore, the Akaike Information Criterion (AIC) and Bayesian Information Criterion (BIC) were used to statistically assess the model's performance and determine its level of acceptance. Next, the basics of wormhole geometries along with the thin-shell formalism are explained in detail. After that, three different wormhole solutions associated with three different choices of the redshift function are presented ,and their various geometric properties as well as energy conditions are studied graphically. Finally, the stability of these thin--shell structures is examined analytically as well as graphically by studying the associated effective potential.
