On the Rate of Convergence of Weak Euler Approximation for Nondegenerate SDEs Driven by Levy Processes

The paper studies the rate of convergence of the weak Euler approximation for solutions to SDEs driven by Levy processes, with Hoelder-continuous coefficients. It investigates the dependence of the rate on the regularity of coefficients and driving processes. The equation considered has a non-degenerate main part driven by a spherically-symmetric stable process

On the rate of convergence of simple and jump-adapted weak Euler schemes for Levy driven SDEs

The paper studies the rate of convergence of the weak Euler approximation for solutions to possibly completely degenerate SDEs driven by Levy processes, with Hoelder-continuous coefficients. It investigates the dependence of the rate on the regularity of coefficients and driving processes. In addition, the rate robustness to the approximation of the increments of the driving process is studied and approximate Euler scheme considered. A rate of convergence is derived for an approximate jump-adapted scheme as well.Comment: A part on approximate jump adapted Euler scheme adde

Interpersonal reletionship characteristic of the coaching process shooting sports coach and their educated 15 – 18 years old adolescents point of view

The object of research - characteristics of interpersonal relations. The issues: What are the main factors which determine the relationships between their coach and the learner? Which characteristics interpersonal relationships are important for the coaches and which for young shooters? Does the interpersonal relationship characteristics are also considered a coach and athlete perspective? Objective of the study - reveal the characteristics of interpersonal relationship between the coaches and their educated 15-18 year old athletes. Research objectives: 1. Explore shooting sports coaches and their learners' ideal and realistic coaches' concepts. 2. Determine gnostic, emotional and behavioral components of shooting sports trainer in communication with the characteristics of learners by gender. 3. Discuss the social distance specifics between shooting sports trainers and their learners. 4. Analyze shooting sports coaches behavioral strategies in conflict situations. The study hypothesis: It is likely that the 15-18 year old athletes approach to interpersonal relations coincides with coaches approach. Conclusions. 1. Shooting sports trainers and learners conceptions of the fundamental characteristics of a real coach substantially didn't differ (p>0,05).Athletes and coaches approach the vision of the ideal coach stood out in various ways. Men and women coaches, athlete girls and women coaches, as well as athletes boys and men coaches views differed significantly (p 0.05). 3. Not determined bold social distance between shooting sports trainers and learners. The vast majority (57.5 percent) of pupils feel that their coach is very friendly. And showed no differences of opinion in this point of view between girls and boys as well. 4. It is noted that the shooting sports coaches women's and men's behavior strategy does not differ in conflict situations,(p> 0.05). Different gender behavioral strategies differ only in the match situations (p<0,05)
