Remarks
In this talk a function is said to have the perfect algebraic independence property if its values at any nonzero algebraic numbers within its natural boundary are algebraically independent and to have the differential perfect algebraic independence property if its values as well as its derivatives of any order at any nonzero algebraic numbers within its natural boundary are algebraically independent. The speaker explained complex entire functions having the differential perfect algebraic independence property, complex functions with natural boundary |z|=1 having the perfect algebraic independence property, complex entire functions represented as infinite products and having the differential perfect algebraic independence property without their zeroes, complex functions of three variables having the perfect algebraic independence property, and functions defined over function fields of positive characteristic and having the differential perfect algebraic independence property.
