Yuav ua li cas tsis yog monotonic ua haujlwm txhaj tshuaj?

Cov haujlwm monotonic no tuaj yeem tsis yog txhaj tshuaj. Yuav txhaj tshuaj muaj nuj nqi yuav tsum yog hom muaj zog ntawm monotony.

Yuav ua li cas txhaj tshuaj?

Hauv kev ua lej, ib qho kev txhaj tshuaj (tseem hu ua kev txhaj tshuaj, lossis ib-rau-ib txoj haujlwm) yog ua haujlwm f uas qhia cov ntsiab lus sib txawv rau cov ntsiab lus sib txawv ; uas yog, f(x1)=f(x2) implies x1=x 2Hauv lwm lo lus, txhua lub ntsiab lus ntawm lub luag haujlwm lub codomain yog cov duab ntawm feem ntau ntawm nws lub npe.

Puas monotonic ua haujlwm tas mus li?

Kev ua haujlwm uas ua kom txaus siab rau qee yam muaj zog monotonicity, thiab kwv yees cov txiaj ntsig nruab nrab, yog pointwise nruam. Tej monotone pointwise nruam muaj nuj nqi yog uniformly nruam. Kev ua haujlwm tsis tu ncua kuj tau txais.
