 Apr9 answered Is the pair $(\{0,4,8,12\},+_{16})$ consist a Group? Apr9 comment Is the pair $(\{0,4,8,12\},+_{16})$ consist a Group? @Omnomnomnom It's a pair consisting of a set and a binary operation. Apr5 comment Fastest way to meet, without communication, on a sphere? You are right.  Apr4 comment Fastest way to meet, without communication, on a sphere? The two could be on non-intersecting orbits like northern and southern polar circles. Apr4 comment Cantor set + Cantor set =$[0,2]$ set = number ?! Mar26 comment Does there exists an automorphism of $\Bbb{C}$ that's also an exponential hom? What is $z^w$ ? Mar23 comment realizing/ understanding $C^*(\phi_g(C([0,1])))$ and "support projection of an element of a $C^*$-algebra Btw, it is not ideal to put two rather unrelated questions into one post. You might consider posting your second question separately. Mar23 comment realizing/ understanding $C^*(\phi_g(C([0,1])))$ and "support projection of an element of a $C^*$-algebra No, but, as you see from my answer, the case where $g$ is invertible is not very interesting.

Mar20 comment A question in Banach space Mar14 comment preserving problem You can easily write down a dense set of bump functions. Mar13 answered preserving problem Mar13 revised preserving problem added 1 character in body Mar12 revised preserving problem edited tags Mar12 comment preserving problem Do you want capital L? Mar12 reviewed Approve preserving problem Mar12 comment are random rotations dense? You have written down a random set. Are you asking whether it is almost surely dense in $[0,1)$?
