Microwave Remote Sensing of Soil Moisture,in . can be uniquely written in the form Σ. .r., where all but a finite number of the elements r. ε . are zero. Free modules can also be described by a ., but the definition given above is more convenient for working inside the free module in question. We can also work with . by identifying it with
