Some Connections Between (Sub)Critical Branching Mechanisms and Bernstein Functions
نویسندگان
چکیده
We describe some connections, via composition, between two functional spaces: the space of (sub)critical branching mechanisms and the space of Bernstein functions. The functions eα : x → xα where x ≥ 0 and 0 < α ≤ 1/2, and in particular the critical parameter α = 1/2, play a distinguished role.

Numerical solution of delay differential equations via operational matrices of hybrid of block-pulse functions and Bernstein polynomials
In this paper, we introduce hybrid of block-pulse functions and Bernstein polynomials and derive operational matrices of integration, dual, differentiation, product and delay of these hybrid functions by a general procedure that can be used for other polynomials or orthogonal functions. Then, we utilize them to solve delay differential equations and time-delay system. The method is based upon e...
متن کاملSolution of Fractional Optimal Control Problems with Noise Function Using the Bernstein Functions
This paper presents a numerical solution of a class of fractional optimal control problems (FOCPs) in a bounded domain having a noise function by the spectral Ritz method. The Bernstein polynomials with the fractional operational matrix are applied to approximate the unknown functions. By substituting these estimated functions into the cost functional, an unconstrained nonlinear optimizat...
متن کاملAnatomic Variations of Brachial Plexus: A Cadaveric Study
Introduction: The brachial plexus is responsible for the innervation to the upper limb and some parts of the thorax. Variations in the branching of the brachial plexus are common and have been reported in 65.3% of the population. The variations (Atypical communication) of brachial plexus have significant clinical and surgical importance. Methods: In this study 10 upper limbs which belonged...
متن کاملThe Different Mechanisms of Action Potential Propagation in the Heart
It was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. Some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (AP). It seems that some other types of mechanisms must be involved in AP propagation. In this article, we...
