The Study of Realities and Prospects of Interaction of Ukraine with European Financial Organizations in the Conditions of Integration Processes
In the article were analyzed the prospects of cooperation between Ukraine and EU structural funds. There was studied the current state of interaction between Ukraine and EIB and EBRD, offered the directions of its optimization. It was proved, that the base of increase of effectiveness of the use of investment resources of European financial organizations by Ukraine and approach of prospects of widening of the credit projects spectrum is not only the clear regulation of the national strategy of economic development but also the improvement of the system of monitoring of the use of investment resources

Minorant methods for stochastic global optimization
We develop numerical methods for solution of stochastic global optimization problems: min and , where x is a finite dimensional decision vector with possible values in the set X, ¦Ø is a random variable, is a nonlinear function of variable x, E and P denote mathematical expectation and probability signs respectively.
These methods are based on the concept of stochastic tangent minorant, which is a random function of two variables x and y with expected value satisfying conditions: (i) , (ii) for all x,y. Tangent minorant is a source of information on a function global behavior. We develop a calculus of (stochastic) tangent minorants.
We develop a stochastic analogue of Pijavski¡¯s global optimization method and a branch and bound method with stochastic minorant bounds.
Applications to optimal facility location and network reliability optimization are discussed

The use of information and communication technologies at lessons discrete mathematics
UK: Метою дослідження є вивчення особливостей застосування інформаційно-комунікаційних технологій при навчанні дискретній математиці. Задачами дослідження є розробити елементи методики комп’ютерної реалізації рішення задач дискретної математики та визначити особливості роботи в середовищі Maple для розв’язування широкого кола завдань. Об’єктом дослідження є навчання дискретної математики. Предметом дослідження є методика використання інформаційно-комунікаційних технологій на заняттях з дискретної математики. В роботі за допомогою функцій пакету networks наведено розв’язання задач з розділу дискретної математики «Теорія графів». На їх прикладі наочно продемонстровано, що для більшості користувачів пакет networks перетворює важкозрозумілі графи в простий робочий інструмент. Результати дослідження – удосконалено методику вивчення теорії графів на основі Maple, візуалізовано побудову графів та видалення деяких їх вершин. EN: The aim is to study the characteristics of information and communication technologies in teaching discrete mathematics. Objectives of the study is to develop the technique for implementing a computer problem solving discrete mathematics and define the features of the environment in
Maple for solving a wide range of tasks. The object of research is teaching discrete mathematics. The subject of research is the method of using ICT in the classroom discrete mathematics. In this work using package ‘networks’ are solving problems of discrete mathematics (section “Graph theory”). By examples is clearly demonstrated that package ‘networks’ can transforms hardto-understand graphs in a simple working tool to the majority of users. Results of the study – improved methodology for the study of graph theory based Maple, visualized build graphs and remove some of their peaks
The Lambda_b lifetime in the light front quark model
The enhancement of the Lambda_b decay width relative to B decay one due to
the difference of Fermi motion effects in Lambda_b and B is calculated in the
light--front quark model with the simplifying assumption that Lambda_b consists
of the heavy quark and light scalar diquark. In order to explain the large
deviation from unity in the experimental result for tau(Lambda_b)/tau(B), it is
necessary that diquark be light and the ratio of the squares of the Lambda_b
and B wave functions at the origin be \le 1.Comment: final journal version to appear in JETP Letter
