To any walk in a quiver, we associate a Laurent polynomial. When the walk is the string of a string module over a 2-Calabi-Yau tilted algebra, we prove that this Laurent polynomial coincides with the ...

Inequalities of Maximum of Partial Sums and Weak Convergence for a Class Weak Dependent Random Variables     $\rho^{-}$-mixing  $\rho^{*}$-mixing  NA  rosenthal type inequalities  weak convergence       font style='font-size:12px;'> 2007/12/12

In this paper, we establish a Rosenthal-type inequality of the maximum of partial sums for $\rho^{-}$-mixing random fields. As its applications we get the H\'{a}jeck--R\`{e}nyi inequality and weak con...
