As we mentioned Whitehead's interests turned more towards topology near the end of his three years in Princeton when he collaborated with Lefschetz in proving that all analytic manifolds can be triangulated.
Bilang namin Whitehead nabanggit ng mga interes gagawing mas patungo sa topology malapit sa dulo ng kanyang tatlong taon sa Princeton kapag siya collaborated sa Lefschetz sa proving na ang lahat ng analytic manifolds ay maaaring triangulated.
