2013/9/3
A Wronskian (resp. Casoratian) criterion is useful to test linear dependence of elements in a differential(resp. difference) field over constants. We generalize this criterion for invertible hyperexpo...

All rings are assumed to be finite commutative with identity element. An element a \in R is called a regular element if there exists b \in R such that a=a2b, the element b is called a von Neumann inve...
