In this paper we prove the existence of dense-range or one-to-one compact operators on a separable Banach space leaving a given finite chain of subspaces invariant. We use this result to prove that a semigroup of bounded operators is reducible if and only if there exists an appropriate one-to-one compact operator such that the collection of compact operators is reducible.

A thermodynamic study on the interaction of bovine carbonic anhydrase II (CAII) with nickel ions was performed by using isothermal
titration calorimetry (ITC) at 27 °C in Tris buffer solution at pH = 7.5. The enthalpies of Ni2+ + CAII interaction are reported and analysed in terms of the new solvation theory. It was indicated that there are three
identical and non-cooperative sites for Ni2+. The binding of a nickle ion is exothermic with dissociation equilibrium constants of 81.306 and 99.126 μM at 27°C and 37°C,
respectively. The binding of nickel ions can cause some changes in the stability of the enzyme at low and high Ni2+ concentrations. 相似文献

In this paper we consider collections of compact (resp. Cp class) operators on arbitrary Banach (resp. Hilbert) spaces. For a subring R of reals, it is proved that an R-algebra of compact operators with spectra in R on an arbitrary Banach space is triangularizable if and only if every member of the algebra is triangularizable. It is proved that every triangularizability result on certain collections, e.g., semigroups, of compact operators on a complex Banach (resp. Hilbert) space gives rise to its counterpart on a real Banach (resp. Hilbert) space. We use our main results to present new proofs as well as extensions of certain classical theorems (e.g., those due to Kolchin, McCoy, and others) on arbitrary Banach (resp. Hilbert) spaces. 相似文献

A thermodynamic study on the interaction of bovine carbonic anhydrase II, CAII, with cobalt(II) and iron(III) ions was made
using isothermal titration calorimetry (ITC) at 300.15 K and 310.15 K in Tris buffer solutions at pH=7.5. The enthalpies of
interaction of Co2++ CAII and Fe3++ CAII are reported and analyzed in terms of the extended solvation theory. The results indicate that there are three identical
and non-cooperative binding sites for Co2+ and Fe3+ ions. Binding of these ions with CAII occurs exothermically with dissociation equilibrium constants of 87.15 and 91.00 μmol⋅L−1 at 300.15 K, for Co2+ and Fe3+, respectively. 相似文献
