It pains me to break this thread by fixing the issue, but here we are. :) We are now inserting \begingroup and \endgroup directives into post and comment bodies, so all command definitions should be scoped to individual posts. For now, I'm only enabling this on Math (and here on meta), but barr...
\name
, they pick also stuff such as \ name
or \,name
. Searching for \C
find also matrix A&B\\C&D
. And I think \C
also picks up \cos

Well, \sqint is the quaternion integral and \fint is used for integral averages, if memory serves. I'll have to look around for the others, though.
It is well known that if $f \in \text{BMO}(\mathbb R^n)$, then for any $\epsilon > 0$ there exists a ball $B$ with center $x_0$ and radius $R$ such that \begin{equation}\label{3} R^\epsilon \int_{\mathbb R^n} \frac{|f(x) - f(B)|}{(R + |x - x_0|)^{n + \epsilon}} \, dx \leq C_{n,\epsilon} \|f\|_*\;...
There are (at least) two ways to interpret your question. The first is that you are asking if the value of the integral is actually given by a Riemann sum. This is not the case, even for Riemann integrable functions. Consider for example the function $$ f:\left[0,1\right]\to\mathbb{R},x\mapsto\be...
\strokedint
or \fint
commands are not implemented in MathJax, so I just replaced it by the definition. — Willie Wong Jul 10 '12 at 11:02I am trying to find $\frac{\partial ^2}{\partial r^2} \frac{1}{|\partial B(x,r)|} \int_{\partial B(x,r)} u(y,t)\mathrm{d}y $ . Where $B$ is a ball of radius $r$ with center at $x$ . Differentiating once was ok , but i couldn't not again differentiate . Thank you for your help .
Some fonts have such an integral sign built in, but if not, you can always stack a - or $-$ over one. \documentclass{article} \usepackage{stackengine} \stackMath \begin{document} $\stackinset{c}{}{c}{}{\mkern1.5mu\mbox{-}}{\int}x\,dx$ $\displaystyle\stackinset{c}{}{c}{}{-\mkern4mu}{\displaystyle...
\fint
) as well as some versions with a horizontal bar.
There is a very useful site for this sort of questions. It is a hand-writing interface to the comprehensive LaTeX symbol list: you draw the symbol you are looking for in a box (using your mouse,...) and the software tries to recognise it. You can teach the software by telling it which one (if a...
\fint
in the esint
package. That package seems to contain a number of ornamented integral signs.
I usually use \fint to denote normalized integration. I would like to produce the same slanted line across a double integral \iint. The command \fiint does not seem to exist. How can I get this notation for normalized double integrals?
