# Closed Operator - Transpose

Let T : B1B2 be an operator between Banach spaces. Then the transpose (or dual) of T is an operator satisfying:

for all x in B1 and y in B2*. Here, we used the notation: .

The necessary and sufficient condition for the transpose of T to exist is that T is densely defined (for essentially the same reason as to adjoints, as discussed above.)

For any Hilbert space H, there is the anti-linear isomorphism:

given by where . Through this isomorphism, the transpose T' relates to the adjoint T∗ in the following way:

,

where . (For the finite-dimensional case, this corresponds to the fact that the adjoint of a matrix is its conjugate transpose.) Note that this gives the definition of adjoint in terms of a transpose.

### Famous quotes containing the word transpose:

We have to transpose ourselves into this impressionability of mind, into this sensitivity to tears and spiritual repentance, into this susceptibility, before we can judge how colorful and intensive life was then.
Johan Huizinga (1872–1945)
