On the Deligne-Simpson problem
The Deligne-Simpson problem is formulated like this: give necessary and sufficient conditions for the choice of the conjugacy classes Cj ⊂ SL(n,C) or cj ⊂ sl(n,C) so that there exist irreducible (p + 1)-tuples of matrices Mj ∈ Cj or Aj ∈ cj satisfying the equality M1 . . .Mp+1 = I or A1 + . . .+Ap+1 = 0. We solve the problem for generic eigenvalues with the exception of the case of matrices Mj ...

متن کاملOn a Question of Brown and Simpson
Brown and Simpson (1993) considered two versions of the Baire Category Theorem, which they called BCT-I and BCT-II . They showed that BCT-I is provable in RCA0, the subsystem of second order arithmetic specifying some basic algebraic properties of the numbers, induction for Σ 1 sets and the recursive comprehension axiom. Additionally, they showed that BCT-II is not provable in RCA0. Brown and S...
متن کاملOn Weighted Simpson Type Inequalities and Applications
In this paper we establish some weighted Simpson type inequalities and give several applications for the r − moments and the expectation of a continuous random variable. An approximation for Euler’s Beta mapping is given as well.
