A Remark on Nets of Threshold Elements
نویسنده
چکیده
The symbols, designations and definitions are the same as those in Krohn and Rhodes (1965); tha t article contains complete algebraic characterizations of general and some special nets of threshold elements and of the transition functions associated with them. In Corollary 3.1. (iii) the authors give a criterion for transition functions of Simple McCulloch-Pitts Nets (SMPN) which is necessary but not sufficient. This paper intends to bring a sufficient criterion by addition of another necessary condition. An example may show that equation (3.1) is not sufficient. Let N = /a, b, c}, a ~ b, a ~ c, b ~ c, and the mapf :$ (N) --~ $(N) be defined by

A remark on boundedness of composition operators between weighted spaces of holomorphic functions on the upper half-plane
In this paper, we obtain a sucient condition for boundedness of composition operators betweenweighted spaces of holomorphic functions on the upper half-plane whenever our weights are standardanalytic weights, but they don't necessarily satisfy any growth condition.
متن کاملA remark on the means of the number of divisors
We obtain the asymptotic expansion of the sequence with general term $frac{A_n}{G_n}$, where $A_n$ and $G_n$ are the arithmetic and geometric means of the numbers $d(1),d(2),dots,d(n)$, with $d(n)$ denoting the number of positive divisors of $n$. Also, we obtain some explicit bounds concerning $G_n$ and $frac{A_n}{G_n}$.

It is pointed out that, one of the results in the recently published article, ’On the Iyengar-Madhava Rao-Nanjundiah inequality and it’s hyperbolic version’ [3] by J´ozsef S´andor is logically incorrect and new corrected result with it’s proof is presented.
متن کاملOn Autonomous Logic Nets of Threshold Elements
A model of autonomous logic nets composed of n threshold elements is presented and several properties of a single threshold element are generalized to this model. The number of these nets is shown to be 2kn (-<k<l) for completely specified machines. The capacity of the net is defined and conjectured to be 2, similar to the case of a single threshold element.
