Learning in teams: peer evaluation for fair assessment of individual contributions
Fedor Duzhin
The "free rider" problem has long plagued pedagogies based on collaborative learning. The most common solution to the free rider problem is peer evaluation. As well other existing…
Lower bounds on the number of closed trajectories of generalized billiards
Fedor Duzhin
Given a domain or, more generally, a Riemannian manifold with boundary, a billiard is the motion of a particle when the field of force is absent. Trajectories of such a motion are…
Lower bounds for the number of closed billiard trajectories of period 2 and 3 in manifolds embedded in Euclidean space
Fedor Duzhin
A lower bound for the number of 3-periodical billiard trajectories in a manifold embedded in Euclidean space is obtained.
On the lower bounds for the number of periodic billiard trajectories in manifolds embedded in Euclidean space
Fedor Duzhin
In this paper the problem of estimating the number of periodical billiard trajectories is considered. The main result is the theorem on Morse theory for periodical billiard traject…
