Partial *-algebras and Volterra convolution of distribution kernels
Giuseppina Epifanio, Camillo Trapanı · Journal of Mathematical Physics · 1991
The set of distribution kernels is considered as a partial *-algebra when the multiplication of two kernels is defined as their Volterra convolution. The partial *-algebra of distribution kernels corresponding to a certain partial *-algebra of closable operators in L2(Ω) is studied.
