Existence and uniqueness of solution of Schrodinger equation in extended Colombeau algebra
M
Alimohammady
F
Fattahi
In this paper, we establish the existence and uniqueness result of the linear
Schrodinger equation with Marchaud fractional derivative in Colombeau generalized algebra.
The purpose of introducing Marchaud fractional derivative is regularizing it in Colombeau
sense.

Product of normal edge-transitive Cayley graphs
A
Assari
For two normal edge-transitive Cayley graphs on groups H and K which have no
common direct factor and gcd(jH=H
′j; jZ(K)j) = 1 = gcd(jK=K
′j; jZ(H)j), we consider four
standard products of them and it is proved that only tensor product of factors can be normal
edge-transitive.

We characterize compact composition operators on real Banach spaces of
complex-valued bounded Lipschitz functions on metric spaces, not necessarily compact, with
Lipschitz involutions and determine their spectra.

Hereditary properties of amenability modulo an ideal of Banach algebras
H
Rahimi
E
Tahmasebi
In this paper we investigate some hereditary properties of amenability modulo an
ideal of Banach algebras. We show that if (e) is a bounded approximate identity modulo I
of a Banach algebra A and X is a neo-unital modulo I, then (e) is a bounded approximate
identity for X. Moreover we show that amenability modulo an ideal of a Banach algebra A
can be only considered by the neo-unital modulo I Banach algebra over A.

A generalized cost Malmquist index to compare the productivities of units with negative data in DEA

Tohidnia
In some data envelopment analysis (DEA) applications, some inputs of DMUs
have negative values with positive cost. This paper generalizes the global cost Malmquist
productivity index to compare the productivity of dierent DMUs with negative inputs in
any two periods of times under variable returns to scale (VRS) technology, and then the
generalized index is decomposed to several components. The obtained components are com-
puted using the nonparametric linear programming models, known as DEA. To illustrate the
generalized index and its components, a numerical example at three successive periods of
time is given.
