Sets are fundamental objects in mathematics. Intuitively, a set is merely a collection of elements or members. There are various conventions for textually denoting sets. In any particular situation, an author typically chooses from among these conventions depending on which properties of the set are most relevant to the immediate context or on which perspective is most useful. Denoting a set as an objectWhere it is desirable to refer to a set as an indivisible entity, one typically denotes it by a single capital letter. In referring to an arbitrary, generic set, a typical notational choice is S. When several sets are being discussed simultaneously, they are often denoted by the first few capitals: A, B, C, and so forth. As another example, there is a nearly universal notational convention that covers certain very important sets of numbers as follows: C The complex numbers N The natural numbers Q The rationals (from quotient) R The reals Z The integers (from German Zahl, for number)Some authors use the blackboard bold font for these particular sets (, , etc.). This usage is widely accepted in handwriting, but many mathematicians, and such experts on mathematical typography as Donald Knuth, advise against its use in print. Another single-character symbol for a set is , which is very widely used to denote the empty set. From Wikipedia under the

Answered by unknown - Thu Jun 21 21:32:15 2007 Where can I get a font for set theory notation? Q. I want to write about set theory and want to use a true type font for the notation. I use MS word for Windows. Where I can I get such a font (free and easy to use)? Asked by Ken D - Sat Oct 6 10:40:32 2007 - - 1 Answers - 0 Comments A. Most of the special symbols you need for mathematical notation are available in the "usual" fonts like Times New Roman if you search for them in "Insert - Symbol ..." For easy access you can allocate shortcut-keys to them. It might be useful to install and/or use few other "usual" fonts like Arial and another one to highlight or set apart some symbols like symbols for sets or objects of a set. These fonts are, I think, included in MS Word. Answered by small monkey - Sat Oct 6 19:08:41 2007 Question about a really odd set notation?
Q. In the question: If x is in/is an element of G(R), is the fourier transform of f also an element of G(R)? Obviously, I don't want anyone to answer the question but what does "x E G(R)" mean? The "E" is the symbol for "is an element of" btw. In the context of the question, I know G is not the antiderivative. Also, R is the set of all real numbers. Is this just a really creative way of saying that G is the set of all real numbers? Asked by Justin D - Sat Mar 29 20:50:13 2008 - - 1 Answers - 0 Comments A. In the sentence, "If x is in/is an element of G(R), is the fourier transform of f also an element of G(R)?" what is the connection between f and x? If f is a function meeting certain properties, than so is the fourier transform of f. Thus one could imagine a set H(R) of all the functions from R (the real numbers) to R which satisfy that set of properties. Then it will be true that if f is H(R), then so is the Fourier transform of f. Furthermore, H(R) is a vector space: if f(x) and g(x) are in H, then so is the function h(x) = af(x) + bg(x) for any real numbers a and b. Thus H(R) is a function space: I don't know anything about a set called G(R), but the above Wikipedia page mentions a space called C-sub-infinity, which does behave… [cont.] Answered by simplicitus - Tue Apr 1 01:01:49 2008 From Yahoo Answer Search: "Set notation" |
