The definition of the modular group is demonstrated by using inhomogeneous linear transformations. With the help of modular group conditions, the upper half-plane is defined with the help of the images under the elements of the modular group ? and the formation of inhomogeneous modular transformations on different transformations is examined. In addition, the theorem about the cases of the modular group has been determined with a distinct method.en10.18185/erzifbed.936882info:eu-repo/semantics/openAccessArticle142453463479548
