A caveat before reading the paper:

As written in the paper, equations (1.3) and (1.6) are consistent each other: Equation (1.3) is the standard way of formally translating the notion of residual income, while equation (1.6) (the EVA model) is just a particular instantiation of equation (1.3). There is no need of using equation (1.8), which is actually incorrect (unless book value of assets coincide with market value of assets). Given that this trivial misprint is totally irrelevant for all arguments, statements, and results in the paper, you may conveniently skip it.

Feel free to contact me (magni@unimo.it).

If the sequence of the Ces` aro means of the iterates of T converges in L(E) endowed with the topology τ b of uniform convergence on bounded sets, the operator T is called

In this section we give a very brief survey of results known to us on the problem of perfect powers in the Fibonacci and Lucas sequences, though we make no claim that our survey

This method is applied actively on various differ- ential equations such as the reaction convection diffu- sion equation [22], Laplace equation [23], generalized nonlinear

In summary, six kinds of new nonclassical potential symmetry generators of the Burgers equation are deter- mined in this paper, and three classes of new explicit solutions are

In summary, based on Yan [21] and Liu and Yang [20], using symbolic computation, we have improved the extended F-expansion method in [20] and proposed the further improved

τ c 2 &lt; β: first, by using the contraction mapping theorem in appropriately chosen spaces, we show a local existence result in some appropriate functional spaces, second by

Theoretical predictions for the fluid branch (BausjColot (7]) and the solid branch (Velasco/Mederos [12)) are compared with experimental data, measured in high-salt

We find that (a) the operational target for carrying out monetary operations at the State Bank of Pakistan happens to be a free reserves target since 2000-01, which, interpreted in
