I don't find the LaTeX command for these symbol

Question

The \gamma like symbol. I searched this in http://detexify.kirelabs.org/classify.html but not found.

@Sigur: I think it is more of a special type of \gamma here... the shown symbol looks more rounded and slanted/italic — , Feb 24 '18 at 16:57
The \mathcal{Q} is similar to the one from times package. But with that the \gamma is completely different. — Sigur, Feb 24 '18 at 17:04
\gamma from the mtpro2 package (a Times Roman clone) comes very very close -- and the \mathcal{Q} and \mathcal{F} characters look right too. — Mico, Feb 24 '18 at 17:06
@alhelal: \mathcal{F} does not really look like Γ .... your question is confusing, since there is a γ in the picture as well — , Feb 24 '18 at 17:07
Since i get \mathcal{F} from DeTeXify, i guess this question can be closed as duplicate. — Johannes_B, Feb 24 '18 at 17:09

@alhelal, so your question was not clear. In title you wrote these but you want for a single symbol. — Sigur, Feb 24 '18 at 17:18
@alhelal Why not simply crop the image to the symbold your interested in? Or mark it? Like this its really confusing! — samcarter_is_at_topanswers.xyz, Feb 24 '18 at 17:18
@Sigur I don't understand why people see only \mathcal{F}. See starting symbol of my image. — alhelal, Feb 24 '18 at 17:23
@alhelal, so why you wrote \mathcal{F} results exactly. For me it means that you wished F. — Sigur, Feb 24 '18 at 17:24
@Sigur as Johannes_B said \mathcal{F}?, so I told him that it is not, it works well. As you noticed that comment you should understand that I didn't ask for that as it works well. — alhelal, Feb 24 '18 at 17:28
A gamma is a gamma; some fonts render it one way, others in a slightly different form. Don't worry and use the one provided by \gamma. — egreg, Feb 24 '18 at 17:30
There are three votes to reopen this question, probably because there is a good answer. But the question as it is, is not worth of reopening before it has been edited. — Johannes_B, Feb 25 '18 at 08:01

A Times Roman text font package (e.g., newtxtext) along with the MathTime Professional 2 math font package (aka mtpro2) will give you the \gamma, \mathcal{Q}, and \mathcal{F} glyphs shown in your screenshot. The curly brace, though, looks much fancier -- it's almost sumptuous -- than the corresponding, rather spindly and sad-looking brace in your screenshot.

\documentclass{article} 
\usepackage{amsmath}
\usepackage{newtxtext}
\usepackage{mtpro2}
\begin{document}
\[
\gamma_{\mathrm{ub}}(\mathcal{Q})=
\begin{cases}
f(\mathbf{c}_{\min}), & \mathbf{c}_{\min}\in\mathcal{F}\\
+\infty,               & \text{otherwise}
\end{cases}
\]
\end{document}

@alhelal - Did you follow the link I provided? The complete mtpro2 package isn't free of charge. However, its lite subset, which is all that's needed to produce the screenshot shown above, may be downloaded free of charge. – Mico Feb 24 '18 at 17:20

@Mico, that should be a miracle.... – Sigur Feb 24 '18 at 17:21
@Mico Do you say to me installing some thing? – alhelal Feb 24 '18 at 17:25

@alhelal - I interpreted your question as asking for a math font (package) that provides an exact match for the \gamma symbol. My answer, I believe, provides such a match. Since mtpro2 isn't a font package that's automatically included with the main TeX distributions, I provided a link to the website from which one may download this math font package. I honestly have no expectations for what you will do with this information. Aside: Downloading and installing this font package (and especially its lite subset) is no more difficult than installing virtually any other package is. – Mico Feb 24 '18 at 17:29
