论文摘要
在本文中，提出了一般相对论框架中的新虫洞解决方案。通过最小的几何变形方法利用引力脱钩，以及所谓的非共同几何高斯和洛伦兹密度曲线的优势，精确的Morris-Thorne时空是最小化的，可提供新的不良蠕虫解决方案。限制某些参数的签名，使用爆炸和能量条件来界定无量纲常数$α$。在这两种情况下，这都会产生违反能量条件的能量量张量，因此时空是通过异国物质进行的。但是，有可能在虫洞喉咙及其邻居处获得正定的密度。为了进一步支持研究，已经进行了彻底的图形分析。
In this article, new wormhole solutions in the framework of General Relativity are presented. Taking advantage of gravitational decoupling by means of minimal geometric deformation approach and, the so-called noncommutative geometry Gaussian and Lorentzian density profiles, the seminal Morris-Thorne space-time is minimally deformed providing new asymptotically wormhole solutions. Constraining the signature of some parameters, the dimensionless constant $α$ is bounded using the flare-out and energy conditions. In both cases, this results in an energy-momentum tensor that violates energy conditions, thus the space-time is threading by exotic matter. However, it is possible to obtain a positive defined density at the wormhole throat and its neighborhood. To further support the study a thoroughly graphical analysis has been performed.
