 Oct 9 asked Lebesgue space and weak Lebesgue space Sep 21 suggested rejected edit on How to simplify $(\sin\theta-\cos\theta)^2+(\sin\theta+\cos\theta)^2$? Jul 2 awarded Curious Jul 2 awarded Inquisitive May 25 comment Application of weak $L^p$ estimate besides for proving boundedness of some linear operator Thank you for your reference. May 24 comment Application of weak $L^p$ estimate besides for proving boundedness of some linear operator May I get the references for your argument (especially about Hardy-Littlewood Maximal operator)? In addition, can the density be applied for fractional integral operator? May 23 asked Relation between fractional integral operator and solution of poisson equation May 23 asked Application of weak $L^p$ estimate besides for proving boundedness of some linear operator May 21 accepted existence of the solution of Neumann problem in $\mathbb{R}^3$ May 11 asked existence of the solution of Neumann problem in $\mathbb{R}^3$ May 11 accepted A function $f:\mathbb{R} \to \mathbb{R}$ with infinite norm but finite weak seminorm Apr 18 answered Is there a difference between limit and “two-sided limit”? Apr 18 accepted Two variable function with four different stationary points Apr 17 comment Two variable function with four different stationary points effective diet pill, Thank you for your example. I hope that I can find simpler example. I think that we can ask, what happen the stationary point if $D=0$ just like $(0,0)$ is the saddle point of $f(x,y)=x^3-y^3$? Apr 12 comment Determine the number of zeros in the first quadrant Just using the quadratic formula and $z=\frac{1}{2}-\sqrt{3}i$ is on the second quadrant Apr 12 answered Determine the number of zeros in the first quadrant Apr 12 comment Two variable function with four different stationary points Thanks @Ian Coley Apr 12 comment Two variable function with four different stationary points Sorry, it is my typo Apr 12 asked Two variable function with four different stationary points Mar 18 comment A function $f:\mathbb{R} \to \mathbb{R}$ with infinite norm but finite weak seminorm @127.0.9.6. Well, after checking again, we have to restrict $q\geq 1$.
