Complex tangents of real surfaces in complex surfaces
Duke Mathematical Journal, 1992 Let \(M\) be a closed real surface, and let \({\mathcal M}\) be a complex manifold of complex dimension two. Let \(\pi:M\to{\mathcal M}\) be an immersion or embedding of \(M\) into \({\mathcal M}\). A point \(p\in M\) is a complex tangent if \(\pi_ *(T_ pM)\) is a complex 1-dimensional subspace of \(T_{\pi(p)}{\mathcal M}\).

Robustness surfaces of complex networks [PDF]
Scientific Reports, 2014 Despite the robustness of complex networks has been extensively studied in the last decade, there still lacks a unifying framework able to embrace all the proposed metrics. In the literature there are two open issues related to this gap: (a) how to dimension several metrics to allow their summation and (b) how to weight each of the metrics.

What Is the Complexity of Surface Integration?
Journal of Complexity, 2001 We study the worst case complexity of computing ε-approximations of surface integrals. This problem has two sources of partial information: the integrand f and the function g defining the surface. The problem is nonlinear in its dependence on g. Here, f is an r times continuously differentiable scalar function of l variables, and g is an s times ...
