I have a few questions about set theory. If you have ana aswer please don't give me a link because it's not explained well enough (wikipedia, scienceworld...).
1. What is a type?
2. What is a group?
3. What is a manyfold? (I read a part of Russell's works and he used the word)
4. How was Rusell's paradox avoided/solved by logicicians and mathematicians? |
