In this paper, we have examined the Kantowski–Sachs space-time in the presence of strange quark matter with the appearance and non-appearance of strings in f(R) gravity. Here, R is the Ricci scalar of the space-time. Exact solutions of the field equations are obtained by considering the following conditions (i) hybrid scale factor, (ii) the proportionality of shear scalar (\(\sigma\)) with expansion scalar (\(\theta\)) and (iii) power-law between the scalar-on function F(R) and average scale factor a(t). We have investigated some physical and geometrical properties of the models, and their behavior is thoroughly studied with the help of graphical representation.

在本文中，我们研究了在奇夸克物质存在的情况下Kantowski-Sachs时空，以及在f（R）重力下弦的出现和不出现。在此，R是时空的Ricci标量。通过考虑以下条件获得场方程的精确解（i）混合比例因子，（ii）剪切标量（\（\ sigma \））与扩展标量（\（\ theta \））和（iii ）的比例）在标量接通函数F（R）和平均比例因子a（t之间的幂律）。我们已经研究了模型的一些物理和几何特性，并借助图形表示对它们的行为进行了彻底的研究。
