infinite fusion app represents a topic that has garnered significant attention and interest. If $S$ is an infinite $\sigma$ algebra on $X$ then $S$ is not countable. 6 Show that if a $\sigma$-algebra is infinite, that it contains a countably infinite collection of disjoint subsets. An immediate consequence is that the $\sigma$-algebra is uncountable. De Morgan's law on infinite unions and intersections.
Example of infinite field of characteristic $p\neq 0$. Similarly, can you give me an example of infinite field of characteristic $p\\neq0$? Finding a basis of an infinite-dimensional vector space?.
For many infinite-dimensional vector spaces of interest we don't care about describing a basis anyway; they often come with a topology and we can therefore get a lot out of studying dense subspaces, some of which, again, have easily describable bases. Proving $\frac {1} {n^2}$ infinite series converges without integral .... Just out of curiosity, I was wondering if anybody knows any methods (other than the integral test) of proving the infinite series where the nth term is given by $\frac {1} {n^2}$ converges.
How to prove the infinite number of sides in a circle?. 0 There is a way of proving that there is "infinite number of sides in a circle", in the following sense. Infinity was a number to both Kepler and Leibniz who spoke of a circle as an infinite-sided polygon. This point of view is useful in analyzing the properties of the circle, as well as more general curves, in infinitesimal calculus.
How can I define $e^x$ as the value of infinite series?. Another key aspect involves, you'll need to complete a few actions and gain 15 reputation points before being able to upvote. Upvoting indicates when questions and answers are useful.
What's reputation and how do I get it? Instead, you can save this post to reference later. linear algebra - Is there a quick proof as to why the vector space of .... Similarly, your further question in the comments, whether a vector space over $\mathbb {Q}$ is finite dimensional if and only if the set of vectors is countable, has a negative answer. If the vector space is finite dimensional, then it is a countable set; but there are infinite-dimensional vector spaces over $\mathbb {Q}$ that are countable as sets.

In relation to this, [duplicate] Ask Question Asked 13 years, 2 months ago Modified 13 years, 2 months ago Infinite product of measurable spaces - Mathematics Stack Exchange. Suppose there is a family (can be infinite) of measurable spaces. What are the usual ways to define a sigma algebra on their Cartesian product?
There is one way in the context of defining product
