The spaces and are ultrabornological a new proof
In  Laurent Schwartz introduced the spaces and of multiplication and convolution operators on temperate distributions. Then in  Alexandre Grothendieck used tensor products to prove that both and are bornological. Our proof of this property is more constructive and based on duality.
