Abstract:
The objects investigated are simply connected pieces of surfaces of positive curvature with isolated flat points. Infinitesimal deformations under given boundary conditions are studied. The deformation situation depends essentially on the order of tangency of the surface with its tangent plane at the flat point, as well as on the index of the boundary condition.
The geometric results are based on the solution of the Riemann–Hilbert problem for generalized Cauchy–Riemann systems with singular coefficients.
