This is the rst article in a series of three where we study some quadratic algebras related to quantized matrix algebras. In the rst part we construct our algebras and relate them to quantized hermitian symmetric spaces. Our point of view is that of non-commutative algebraic geometry 1] and for this reason we determine the associated variety of a certain(More)
How do firms respond to technological advances that facilitate the automation of tasks? Which tasks will they automate, and what types of worker will be replaced as a result?
