Hans-Jürgen Stan,Manfred Linkerhägnerd the identity operator . is the unit (neutral element of multiplication) of this algebra. The operation of passing to the adjoint operator . is an anti-linear, anti-multiplicative . (for any . we have .. = .). Moreover, the operator norm is compatible with algebra structure in the sense that . In p

Analysis of Macroevolution with Phylogenies,roduced in a context much wider than the theory of operators on Hilbert spaces by S.L. Woronowicz (see [., .]). As we already mentioned a couple of times, the .-transform is a way to encode full information about a given closed densely defined operator . in a bounded operator ... The procedure of pa

Analysis of Macroevolution with Phylogenies,culus which can be defined exclusively using the .-transform. Next we will move on to Borel functional calculus and finally assign to each self-adjoint operator its spectral measure and discuss functional calculus for unbounded functions.
