Unbounded operators on Hilbert C*-modules
Unbounded operators on Hilbert C*-modules
Let E and F be Hilbert C*-modules over a C*-algebra ๐. New classes of (possibly unbounded) operators t : E โ F are introduced and investigated. Instead of the density of the domain ๐(t) we only assume that t is essentially defined, that is, ๐(t) โฅ = {0}. Then t โฆ
