May10 answered is this vector field conservative? May10 answered Calculus question about conservative vector fields Mar31 comment question about the oscillation of a function at a point You are right! I feel so stupid. However, You mentioned that it is monotone decreasing. I think it is increasing? Mar31 comment question about the oscillation of a function at a point Sorry to bother you Professor Shifrin, but I still don't see why $\omega( \delta )$ is bounded below. Can you explain a little bit more ? Mar31 comment question about the oscillation of a function at a point can the limit be infinite ? Mar31 comment question about the oscillation of a function at a point Well if $\delta < \delta'$, then $B(x_0, \delta) \subseteq B(x_0, \delta ' )$ taking sups, we have $\omega(\delta) < \omega( \delta')$ ? so $w$ is monotone. but how can this tells me that the limit exists? Mar31 asked question about the oscillation of a function at a point Mar30 asked Continuity of a function on a box $Q$ implies integrability Mar24 accepted Geometry question regarding existence of a quadrilateral Mar23 accepted graph of a continuous function is closed Mar22 asked Discontinuity of the characteristic function Mar22 asked graph of a continuous function is closed Mar20 comment If you toss $1000$ fair coins $10$ times each, what is the probability the *some* coin will get $10$ heads? pure genius Brian.
