More integration theoryeasures can be constructed from old ones. If (., .) and (., .) are measurable spaces, then a set of the form . × ., where . ∈ . and . ∈ ., is called a . in . × .. The .-ring of subsets of . × . generated by the collection of all measurable rectangles is denoted by . × ., and the space . × . equipped

The open mapping theoremeses, a continuous mapping must be open. (For one-to-one mappings this is equivalent to the assertion that the inverse mapping is also continuous.) The reader is already familiar with one theorem of this type, viz., the theorem asserting that a continuous and one-to-one mapping of a compact topologi

Dualityers to be discussed here, however, are most useful and most easily understood in the context of Banach spaces (where a natural topology, viz., the norm topology, exists on .*); accordingly, we shall focus our attention principally on that important special case. However, in order not to restrict unn

Klaus Plakeances. In other words, agency is not a simple property of a subject or thing. It is an important concept for HCI and activity theory because of the principle of mediation. Entities mediate according to the kinds of agency they are capable of.

Rumänien ist kein Entweder-Oder, sondern ein Sowohl-Als-Auch.
