Whitney's local holomorphic lamination conjecture for analytic varieties

About 19 years old · traced to

Let VV be an analytic variety in Cn\mathbb C^n and let XX be a stratum of an analytic stratification of VV. For every point p∈Xp\in X, there should exist a neighborhood UU of pp in VV, a metric space TT, and a homeomorphism

ϕ:(X∩U)×T⟶U\phi:(X\cap U)\times T\longrightarrow U

such that, for every t∈Tt\in T, the restriction of ϕ\phi to (X∩U)×{t}(X\cap U)\times\{t\} is biholomorphic onto its image, the differentials of these restrictions are continuous on (X∩U)×T(X\cap U)\times T, and the lamination generated by ϕ−1\phi^{-1}, of the same dimension as XX, is coherent with all the strata. Whitney's conjecture. Every analytic variety VV of Cn\mathbb C^n supports an analytic stratification with these properties. This is a local-triviality-type assertion for analytic stratifications, requiring holomorphic leaves and coherence with all strata; the source attributes the conjecture to H. Whitney (1965), while noting that Whitney's result gives a bb-regular analytic stratification.
