Values of ScalersDate: 9/11/96 at 12:58:1 From: Anonymous Subject: Values of Scalers As defined, can a scalar quantity be negative? Date: 9/12/96 at 14:15:56 From: Doctor Ceeks Subject: Re: Values of Scalers Hi, The notion of scalar generally refers to an element in a field. If the field is the field of real numbers, or a subfield of the real numbers, than a scalar can be negative. But if the field has no notion of negative number, such as for a finite field, or the field of complex numbers, then a scalar quantity cannot be said to be negative or positive. Some books may implicitly assume that all fields are real, however, and may then use "negative scalars" without explanation. What definition of scalar are you working with? -Doctor Ceeks, The Math Forum Check out our web site! http://mathforum.org/dr.math/ |
