The interaction of the asymmetrical screw flows for the Bryan-Pidduck model
Journal Title: Математичні Студії - Year 2018, Vol 50, Issue 2
Abstract
Some approximate solutions of the Boltzmann equation for a model of rough spheres are constructed. Several sufficient conditions which minimize the uniform-integral error between parts of the Bryan-Pidduck equation are obtained.

Two remarks on the book by Roman Duda “Pearls from a Lost City. The Lvov School of Mathematics”
We consider the murder of Lviv professors and students in July 1941, mentioned in the book by Roman Duda “Pearls from a Lost City. The Lvov School of Mathematics".
On the growth of Laplace-Stieltjes integrals
In the paper it is investigated the growth of characteristics of Laplace-Stieltjes integrals I(σ)=∫+∞0f(x)dF(x), where F is a nonnegative nondecreasing unbounded function continuous on the right on [0,+∞) and f is a nonn...
Problem of determining of minor coefficient and right-hand side function in semilinear ultraparabolic equation
The problem of determining of the right-hand side function and the time depended minor coefficient in semilinear ultraparabolic equation from the initial, boundary and overdetermination conditions, is considered in this...
Entire curves having bounded l-index in ℓ∞
In this paper we propose an approach to introduce a concept of bounded index in an infinite-dimensional space. Our object of investigation is the space ℓ∞ equipped with the norm ∥x∥∞=sup{|xn|:n∈N}. We consider entire cur...
Fast growing meromorphic solutions of the systems of linear differential equations
Systems of linear differential equations that allow for dimension decrease are considered. Growth estimates for meromorphic vector-solutions are obtained. An essentially new feature is that there are no additional constr...
