General Quantum Variational Calculus (eBook, PDF)

• Format: PDF

Produktbeschreibung

Quantum calculus is the modern name for the investigation of calculus without limits. The quantum calculus or q-calculus began with FH Jackson in the early twentieth century, but this kind of calculus had already been worked out by Euler and Jacobi.
