For a tetrahedron, suppose that all internal angles of faces and dihedral are less than fixed constant $C$ is smaller $\pi$. Then, it said to satisfy the maximum angle condition with $C$. The important in error analysis Lagrange interpolation on tetrahedrons. This ensures we can obtain an estimation, even certain kinds anisotropic In this paper, using two quantities represent geometry tetrahedr...

We introduce a new class of Backward Stochastic Differential Equations in which the T -terminal value YT of the solution (Y, Z) is not fixed as a random variable, but only satisfies a weak constraint of the form E[Ψ(YT )] ≥ m, for some (possibly random) non-decreasing map Ψ and some threshold m. We name them BSDEs with weak terminal condition and obtain a representation of the minimal time t-va...

A variety of syntactic phenomena seem to involve a ban on multiple adjacent identical objects. I develop a theory of phenomena of this type, positing a constraint on linearization at the syntax-phonology interface which prevents linearization of structurally adjacent syntactic objects with the same label. The claim is that linearization statements make reference only to node labels, not to part...

The experimental observation of effects due to Berry’s phase in quantum systems is certainly one of the most impressive demonstrations of the correctness of the superposition principle in Quantum Mechanics. Since Berry’s original paper in 1984, the spin 1/2 coupled with rotating external magnetic field has been one of the most studied model where those phases appear. We also consider a special ...
