The P-values for both proposed tests are much smaller then in the case of other known tests. Differently from the test of Stablein and Koutrouvelis the new tests can be applied not only for singly but also to randomly censored data.}, language = {en} } @unpublished{LyTarkhanov2007, author = {Ly, I. and Tarkhanov, Nikolai Nikolaevich}, title = {The cauchy problem for nonlinear elliptic equations}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-30228}, year = {2007}, abstract = {This paper is devoted to investigation of the Cauchy problem for nonlinear elliptic equations with a small parameter.}, language = {en} } @unpublished{CalvoSchulze2005, author = {Calvo, D. and Schulze, Bert-Wolfgang}, title = {Edge symbolic structures of second generation}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-29940}, year = {2005}, abstract = {Operators on a manifold with (geometric) singularities are degenerate in a natural way.
