On the Potential Theoretic Aspect of Alexandrov Surface Theory,rs—amongst whom, most notably Wintner [.] and [.], Chern–Hartman–Wintner [.], and Reshetnyak [.] (Chap. .)—have sought to determine the weakest possible conditions under which the existence of such coordinate systems may be proven.

How I Got Involved in Research on Two-Dimensional Manifolds of Bounded Curvature,In the thirties of the last century, a new bright figure appeared on the horizon of Soviet mathematics: Aleksandr Danilovich Alexandrov. He was an actively working young mathematician, a man with outstanding talent and bright temperament. He is the author of research on the theory of convex bodies, continuing the work of H. Minkowski.

Isothermal Coordinates on Manifolds of Bounded Curvature,The notion of two-dimensional manifolds of bounded curvature was introduced by A. D. Alexandrov in [.,.,.,.].

Isothermal Coordinates on Manifolds of Bounded Curvature II, The present second part of the article is devoted to the proof of three basic lemmas stated in [.] (Chap. .). The definitions of the main notions and the terminology adopted in [.] (Chap. .) are supposed to be known in what follows.

Turn of Curves in Manifolds of Bounded Curvature with Isothermal Metric,A. D. Alexandrov [., .] introduced an important class of metric spaces—two-dimensional manifolds of bounded curvature. The theory of these spaces was developed in detail by A. D. Alexandrov in cooperation with V. A. Zalgaller. The main results of this theory are explained in the monograph [.].
