In the present paper, authors study strange stars with MIT Bag EoS admitting Buchdahl symmetry (non-singular and physically viable metric potential) in both linear $$f(Q)=aQ+b$$ nonlinear $$f(Q)=Q+aQ^b$$ forms of modified symmetric teleparallel gravitation. order to obtain correct form coefficients, they matched interior star space-time exterior Schwarzschild vacuum space-time. As a candidate, ...

Let denote the class of connected plane bipartite graphs with no pendant edges. A finite face s of a graphG ∈ is said to be a forcing face ofG if the subgraph ofG obtained by deleting all vertices of s together with their incident edges has exactly one perfect matching. This is a natural generalization of the concept of forcing hexagons in a hexagonal system introduced in Che and Chen [Forcing ...
