On the Signature of a Path in an Operator Algebra
We introduce a class of operators associated with the signature of a smooth path 𝑋 with values in a 𝐶⋆ algebra 𝒜. These operators serve as the basis of Taylor expansions of solutions to controlled differential equations of interest in noncommutative probability. They are defined by fully contracting...
