Tautological bundles are constructed both in algebraic topology and in algebraic geometry. Not all logical consequences are tautological consequences. Conventional mathematical logic consists of tautological formulae, signalled by a prefixed turnstile. Stove claims that Berkeley tried to derive a non-tautological conclusion from tautological reasoning. However, much care would be needed to disentangle tautological from testable aspects. Real projective space has a natural line bundle over it, called the tautological bundle. However, building a substantive argument based on a tautological foundation is problematic. The correspondence between Lagrangian and Hamiltonian mechanics is achieved with the tautological one-form. He argued that mathematical economics suffered from being tautological. Many scholars have argued that the dynamic capability theory is vague and tautological . This occurs for the same linguistic reasons that cause many toponyms to be tautological. Let formula 52 denote the tautological 1-form on formula 50. The notion of the tautological one-form is commonly used in this setting. Darwin's theory of adaptation through natural selection was accused of being tautological. This line bundle is called the tautological line bundle.
