Uniform boundedness of pretangent spaces and local strong one-side porosity
Viktoriia Bilet, Oleksiy Dovgoshey
Let (X,d,p) be a pointed metric space. A pretangent space to X at p is a metric space consisting of some equivalence classes of convergent to p sequences (x_n), x_n \in X, whose de…

Pretangent spaces with nonpositive and nonnegative Aleksandrov curvature
Viktoriia Bilet, Oleksiy Dovgoshey
We find conditions under which the pretangent spaces to general metric spaces have the nonpositive Aleksandrov curvature or nonnegative one. The infinitesimal structure of general…
