Sinopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, more specifically functional analysis and operator theory, the notion of unbounded operator provides an abstract framework for dealing with differential operators, unbounded observables in quantum mechanics, and other cases. The term unbounded operator" can be misleading, since: "unbounded" should be understood as "not necessarily bounded" "operator" should be understood as "linear operator" (as in the case of "bounded operator") the domain of the operator is a linear subspace, not necessarily the whole space (in contrast to "bounded operator") this linear subspace is not necessarily closed often (but not always) it is assumed to be dense in the special case of a bounded operator, still, the domain is usually assumed to be the whole space."
