Abstract: ABSTRACT: This work concentrates on the Euler characteristic of groups and points out that, this number can also be a rational one. We give some background material on the Euler theorem and the relevant topics. We also review the Fundamental Group and the Covering Space theories. We give C.T.C. Wall’s definition for the Euler characteristic of a group. We fill in the gaps in the proofs of certain formula given under the notions of L-class and M-class. Finally, we describe the exact structure of subgroups of free products of groups via some examples. Keywords: Euler characteristic, Euler theorem, Fundamental Group Theory, Covering Space Theory, C.T.C. Wall’s definition, L-class, M-class, free products of groups. …………………………………………………………………………………………………………………………………………………………………………………………………………………… ÖZ: Bu çalışmada grupların Euler karakteristiği baz alınarak, C.T.C. Wall’un bu sayının rasyonel olabileceğini gösterdiği çalışması irdelenmiştir. Euler Teorem’in temel özellikleri ve ilgili konuları verildi. Bunun yanında, Temel Gurup ve Örtü Uzayları Teorileri özetlendi. Gurupların Euler karakteristikleri için C.T.C. Wall’un tanımı verildi ve hemen ardından L ve M sınıfları için formüller ispatlandı. En son olarakta, serbest grupların alt gruplarının yapısı örneklerle incelendi. Anahtar Kelimeler: Euler karakteristik, Euler teorem, Temel Gurup Teorisi, Örtü Uzayları Teorileri, L ve M sınıfları.
