On some classes of continious mappings of subsets of Hilbert space. II

The paper contains some important properties of cl asses of continuous mappings of subsets of real Hilbert space $H$, introduced in [1], for construction of an infinite-dimensional algebraic topology in space $H$. The concept of topological degree for mappings from the class $K$ and the concept of $K$-infinite-dimensional homotopic groups for subsets of Hilbert space $H$ are defined.
