It is closely related with and strongly uses results of R. Borcherds. This theory should generalize well-known Theories of finite Kac–Moody algebras (i. e. classical semi-simple Lie algebras corresponding to positive genera...

Using a unique dataset of bankrupt firms from India, we show insiders manage earnings downward before filing for bankruptcy via inventory and trade receivable accruals.

Mobile networks originally had no real security which proved to be a deployment that was attacked constantly and the providers were defrauded of millions of dollars. To address t...
