Query: Subvarieties of hypercomplex manifolds with holonomy in SL(n,H)   A hypercomplex manifold M is a manifold with a triple I,J,K of complex
structure operators satisfying quaternionic relations. For each quaternion L=aI
+bJ+cK, L^2=-1, L is also a complex structure operator on M, called an induced
complex structure. We are studying compact complex subvarieties of (M,L), when
L is a generic induced complex structure. Under additional assumptions (Obata
holonomy contained in SL(n,H), existence of an HKT metric), we prove that (M,L)
contains no divisors, and all complex subvarieties of codimension 2 are
trianalytic (that is, also hypercomplex).
