Euler–Lagrange-Type Equations for Functionals Involving Fractional Operators and Antiderivatives
The goal of this paper is to present the necessary and sufficient conditions that every extremizer of a given class of functionals, defined on the set C1[a,b], must satisfy.

Construction of controllability function as time of motion
This article is devoted to the controllability function method in admissible synthesis problems for linear canonical systems. The work considers methods of constructing such control so that the controllability function is time of motion of an arbitrary ...

An m-Polar Fuzzy PROMETHEE Approach for AHP-Assisted Group Decision-Making
The Analytical Hierarchy Process (AHP) is arguably the most popular and factual approach for computing the weights of attributes in the multi-attribute decision-making environment. The Preference Ranking Organization Method for Enrichment of Evaluations (

Investigation of gobal stability of the equilibrium position of a system of differential autonomous equations with the help of admissible functions [PDF]
To study the global stability of the zero solution, which is a single rest point for a nonlinear system of autonomous differential equations, admissible functions are used. These functions are analogous to Lyapunov functions, but do not coincide with them. Admissible functions can also be used for study the global stability of the zero solution of such

Positive decomposition of transfer functions with multiple poles [PDF]
We present new results on decomposing the transfer function t(z) of a linear, asymptotically stable, discrete-time SISO system as a difference t(z) = t(1)(z) - t(2)(z) of two positive linear systems.

Minimal positive realizations of transfer functions with nonnegative multiple poles [PDF]
This note concerns a particular case of the minimality problem in positive system theory. A standard result in linear system theory states that any nth-order rational transfer function of a discrete time-invariant linear single-input-single-output (SISO)

Algorithm for positive realization of transfer functions [PDF]
The aim of this brief is to present a finite-step algorithm for the positive realization of a rational transfer function H(z). In comparision with previously described algorithms we emphasize that we do not make an a priori assumption on (but, instead,

On the minimization of some nonconvex double obstacle problems
We consider a nonconvex variational problem for which the set of admissible functions consists of all Lipschitz functions located between two fixed obstacles.
