wish to replicate a symbol seen in an equation

Question

i have a image and i want to write equation from the image
how i can write g in equation ?

at first i write g_{vix}\left ( s \right ) but g is not like g on the image

Check here first, but that looks like a \mathcal{g}_{\mathrm{vis}} (S). I’m not sure which \mathcal font. — Davislor, May 11 '20 at 15:13

If you will add \usepackage{newtxtext) is the same of the picture. Very good. – Sebastiano May 11 '20 at 15:24
Thanks. Shall I rephrase? – MadyYuvi May 11 '20 at 15:58

No. It is only a suggestion if you wanted use Times New Roman fonts instead of the classic computern modern (CM) for the text. It is perfect. – Sebastiano May 11 '20 at 20:04
