WebDec 18, 2024 · A formal scheme is a formal neighbourhood of a scheme, a scheme with infinitesimal thickening. Generally this may be formalized via ind-objects of schemes. … WebIn the algebraic setting, there is an intermediate construction between an algebraic group and its Lie algebra, given by the formal group. One completes the algebraic group along the identity to get a formal scheme equipped with a group law, and one can pass from there to the tangent space to get the Lie algebra. men\u0027s health facts 2021
