We study the (3+1)-dimensional p-wave holographic superconductors with Weyl corrections both numerically and analytically. We describe numerically the behavior of the critical temperature Tc with respect to charge density ρ in a limited range of Weyl coupling parameter γ and we find in general that the condensation becomes harder with the increase of the parameter γ. In the strong-coupling limit of Yang-Mills theory, we show that the minimum value of Tc obtained from the analytical approach is in good agreement with the numerical results, and finally show how we got remarkably a similar result for the critical exponent of the chemical potential μ and the order parameter⟨J1x⟩ with the numerical curves of the superconductors.
