Dendrimers are the unique chemical trees with maximum spectral radius
(Univ Kragujevac, 2012)
It is shown that dendrimers have maximum spectral radius and maximum Collatz-Sinogowitz index among all chemical trees of given size. The result is also generalized for the class of chemical trees with prescribed number ...
Harmonic function for which the second dilatation is ?-spiral
(Springer International Publishing AG, 2012)
Let f = h + (g) over bar be a harmonic function in the unit disc . We will give some properties of f under the condition the second dilatation is alpha-spiral.
Comment on "Encryption and decryption of images with chaotic map lattices" [Chaos 16, 033118 (2006)]
(American Institute of Physics Inc., 2008-09)
In this paper, we comment on the chaotic encryption algorithm proposed by A. N. Pisarchik et al. [Chaos 16, 033118 (2006)]. We demonstrate that the algorithm is not invertible. We suggest simple modifications that can ...
On the third boundary value problem for parabolic equations in a non-regular domain of R? +1
(Işık University Press, 2016)
In this paper, we look for sufficient conditions on the lateral surface of the domain and on the coefficients of the boundary conditions of a N?space dimensional linear parabolic equation, in order to obtain existence, ...
