Products and Convolutions in Hermite-Sobolev spaces

Suprio Bhar, Rajeev Bhaskaran

In this paper, we show that the product, or equivalently the convolutions of two functions in the Hermite-Sobolev spaces is again in the same space, f…

Pathwise Itô isometry for scaled quadratic variation

Suprio Bhar, Purba Das, Barun Sarkar

The concept of scaled quadratic variation was originally introduced by E. Gladyshev in 1961 in the context of Gaussian processes, where it was defined as the limit of the covarianc…
