In this paper, we prove three common fixed point theorems for weak contraction mappings of integral type in
modular spaces. In the first theorem we prove a common fixed point of ρ-compatible mappings satisfying a (ϕ - Ψ)-weak
contraction. The second theorem is another version of the first theorem. In the third theorem we study a common fixed point
of ρ-compatible mappings in modular spaces involving altering distances of integral type. The results extended several
similar results in metric and Banach spaces.
