Henstock–Kurzweil delta and nabla integrals ✩

We will study the Henstock–Kurzweil delta and nabla integrals, which generalize the Henstock–Kurzweil integral.Many properties of these integrals will be obtained. These results will enable time scale researchers to study more general dynamic equations. The Henstock–Kurzweil delta (nabla) integral contains the Riemann delta (nabla) and Lebesque delta (nabla) integrals as special cases. © 2005 Elsevier Inc. All rights reserved
