Set-valued differentiation as an operator
Serguei Samborski
We introduce real vector spaces composed of set-valued maps on an open set. They are also complete metric spaces, lattices, commutative rings. The set of differentiable functions i…

On Metric Completness and Completness in sense of Lattices
Serguei Samborski
We give an answer to the following question: for which metric in an abstract lattice the completion as a metric space coincides with the completion as a lattice. We obtain the answ…

On Linearity of Nonclassical Differentiation
Serguei Samborski
We introduce a real vector space composed of set-valued maps on an open set X and note it by S. It is a complete metric space and a complete lattice. The set of continuous function…
