Abstract

top
Let K be a field. The generalized Leibniz rule for higher derivations suggests the definition of a coalgebra 𝒟 K k for any positive integer k . This is spanned over K by d 0 , ... , d k , and has comultiplication Δ and counit ε defined by Δ ( d i ) = ∑ j = 0 i d j ⊗ d i - j and ε ( d i ) = δ 0 , i (Kronecker’s delta) for any i . This note presents a representation of the coalgebra 𝒟 K k by using smooth spaces and a procedure of microlocalization. The author gives an interpretation of this result following the principles of the quantum theory of geometric spaces.
