Abstract Various attempts have been made in defining the derivative of a quaternionic function due to the noncommutativity of the product over quaternions. We observe that the difference in the left and right operations caused by the noncommutativity of the quaternion product is determined by the vector part of the quaternion. In this paper. we propose a corresponding derivative to re... https://bxxrnqd57cnjl.theisblog.com/35130279/epimerization-of-ergot-alkaloids-in-feed
