Abstract Let (X, T) and (Y, S) be two topological dynamical systems, and π: X→ Y a factor map. Let a=(a 1, a 2)∈ R 2 with a 1> 0 and a 2≥ 0, and f∈ C (X). We define the a-weighted topological pressure of f, denoted by P a (X, f), as an extension of the classical topological pressure. In this approach, we use the a-weighted Bowen balls to substitute the Bowen balls in the classical definition. We prove the following variational principle: P a (X, f)= sup{a 1 h μ (T)+ a 2 h μ∘ π− 1 (S)+∫ f d μ}, where the supremum is taken over the T-invariant measures on X. It not only generalizes the variational principle of classical topological pressure, but also provides a topological extension of dimension theory of invariant sets and measures on the torus T 2 under affine diagonal endomorphisms. A higher dimensional version of the result is also established.
