Involution Matrices of Real Quaternions

An involution or anti-involution is a self-inverse linear mapping. In this paper, we will present two real quaternion matrices, one corresponding to a real quaternion involution and one corresponding to a real quaternion anti-involution. Moreover, properties and geometrical meanings of these matrices will be given as reflections in R^3.

Outlines of Enzyme Chemistry

lesions tend to have relatively large numbers of tubercle bacilli present, whereas others tend to have very few. However, the variations in the number of bacilli found in any one type of lesion is often so great that the average does not give a true picture of the situation. In one instance, for example, a series of 19 lesions were studied in which the bacterial content varied from 0 to 20,000 ...

Outlines of General Psychopathology

This is a lucid and systematic exposition of the subject matter, relationships and aims of psychopathology. Dr. Malamud points out that though this science has a definite and special value in its own field, yet, as its close approximation to other branches of science, such as medicine, psychopathology and education, alone indicates, its ramifications are both complex and diverse. None the less,...

Outlines of Elementary Botany

As a general rule, we are opposed to Scientific Manuals, for the use of students, which treat in an elementary way of the scicnces whose principles and bearings it is the student's duty to master during his university career. We are opposed to them because, from their elementary nature, they contribute to convey to his mind a false impression of the limits of the science and of its relations to...
