Next section 4 develops the notion of reduced Witt vectors; this is used to compute the Artin-Schreier-Witt symbol in section 5 and thus to describe the ramification groups for
This criterion has been already applied in the case of 1-dimensional local fields to describe the structure of the ramification filtration modulo commutators of order ≥ p [1, 2],
As the main result (Theo- rem 3.1), we give a complete solution of Problem 1.1 in the case when the eigenvalues of the matrix (1.2) belong to F , and F is an infinite field..
It is known that for a totally positive (TP) matrix, the eigenvalues are positive and distinct and the eigenvector associated with the smallest eigenvalue is totally nonzero and has
So in this work we study BSDEs with two reflecting barriers driven by a Brownian motion and an independent Poisson measure.. This is the natural extension of Hamad`ene &
We now see that the flow compensator Λ of N (on [0 , 1] 2 ) characterizes the law of the point process in two extreme cases: the totally ordered point process (all jump points
However, comparing this with the bound cL/x α of Theorem 1, we see that there is an important discrepancy when M is large, and so it is natural to investigate the case when x α lies
Finally, we note that the proof of the convergence (3) of Theorem 2 (which is given in Section 4) works as it is, when we start the Markov chain with a translation invariant
