Mathematics display is plain.

[Borbonjuggler]

First of all, thanks for taking the ti,e for putting together a new beamer theme, I do not understand the reason the math seem so plain.

I declare a shorthand for the vectors and matrices:

this is the code I used for creating the slide :

as you see the final is plain no difference with the normal text.

Do you mean the font seems same as the text? You can update that by changing the font for maths environment.

Ratul, thanks for replying. you are right, that it is what I meant, that there is no visual difference between the math fonts and the normal text. I have done as you suggested but no change. would you suggest me how to do it?

In presento.sty

comment the line 43:

\setmainfont[Ligatures=TeX,Path=fonts/,BoldFont=NotoSans-Bold,ItalicFont=NotoSans-Italic,BoldItalicFont=NotoSans-BoldItalic,SmallCapsFont=AlegreyaSansSC-Regular]{NotoSans-Regular}

and add what you just wrote:

\usefonttheme[onlymath]{serif}

and the math formulas will be like with serif like in regular LaTeX
