Show that $\nexists $ does not exist (I did not find the symbol in latex) $ f: S^{m}->S^{n}$
continuous application $m > n$ $Af=fA$ if and only if it does not exist $ g: S^{n+1}->S^{n}$
keep going $Ag=gA$

Please show us what you have tried and exactly where you are stuck.

Instead of using dollar signs you will need to use [ math ] and [ /math ] brackets.

[ math ]\exists ~ \nexists[ /math ] gives [math]\exists ~ \nexists[/math] (Just leave out the spaces next to the "math"s.)
