The combinatorics of splittability

, 2004
Marion Scheepers, in his studies of the combinatorics of open covers, introduced the property Split(U,V) asserting that a cover of type U can be split into two covers of type V. In the first part of this paper we give an almost complete classification of

Some new directions in infinite-combinatorial topology

, 2006
We give a light introduction to selection principles in topology, a young subfield of infinite-combinatorial topology. Emphasis is put on the modern approach to the problems it deals with. Recent results are described, and open problems are stated.

Stein's method and Poisson process approximation for a class of Wasserstein metrics

, 2009
Based on Stein's method, we derive upper bounds for Poisson process approximation in the $L_1$-Wasserstein metric $d_2^{(p)}$, which is based on a slightly adapted $L_p$-Wasserstein metric between point measures.

Influence of hereditarity on arterial hypertension in post-exercise hypotension

, 2022
To verify the cardiovascular response of normotensive men with positive family history of arterial hypertension from the mother and of normotensive men with positive family history of arterial hypertension from the father after an aerobic exercise session. Were selected 35 adult men divided into groups: HF+mother (only mother with arterial hypertension,

Stochastic Delay Equations with Hereditary Drift: Estimates of the Density

Journal of Functional Analysis, 2000
The authors study a one-parameter family of stochastic differential delay equations of the form \[ X^\varepsilon(t) = \int_0^tH(s, X^\varepsilon_s)ds + \varepsilon\int_0^tg(s, X^\varepsilon(s - r)) dW(s),\quad t \geq 0,\tag \(*\) \] with deterministic initial condition \(X^\varepsilon(t) = \eta(t), t \in [-r, 0]\). Here \(r\) is a fixed time delay and \

Remark to history of fractional derivatives on complex plane: Sonine-Letnikov and Nishimoto derivatives

, 2016
An important part of fractional calculus is connected with the fractional-order integrodifferentiation in the complex plane, which is generalization of the well-known Cauchy differentiation formula.
