@emeth: :-) Actually, I have engaged in serious research in theoretical mathematics for quite a few years, so I know something about conducting it. I don't read or understand German, so I hesitated to move in that direction. Nor did I want to rely exclusively on Wikipedia and/or WTS sources with their well-known inaccuracies and other lacunae. Those were the chief reasons I enlisted the help of others and was very pleased to have received it. But you might want to learn a little more about a person before you pillory their character or abilities. If you learn to offer your assistance without looking down your nose at others, you will accomplish a lot of good. As Abraham Lincoln said once, "You'll draw more flies with a drop of honey than you will with a gallon of gall (vinegar)." That being said, I want to thank you again for your answers to my question. My gratitude goes as well to everyone else who contributed to this thread.
Best,
Quendi
