Don't use % if you want to write the % character directly. The % character is reserved to indicate a comment after which everything is ignored. This is no problem at the end of a line, but the % should not occur in between, say, $11 %$, because this way TeX has entered math mode which is not correctly closed (unless there's a stray $following in one of ... 2 Here is a \uhref command for selectively underlining the text: \documentclass{article} \usepackage{etoolbox} \usepackage{hyperref} \makeatletter \newif\ifunderlinehref \DeclareRobustCommand{\uhref}{\underlinehreftrue\href} \patchcmd{\hyper@link@} {{\Hy@tempb}{#4}} {{\Hy@tempb}{\ifunderlinehref\underline{#4}\else#4\fi}} {}{} \apptocmd{\hyper@link@} ... 2 Well, one way to fix the problem is to change the position of the \underline so that it is placed within the second argument of the href. The answer, then, becomes: \documentclass{article} \usepackage{hyperref} \begin{document} 1 (without \#, link, underlined) = \underline{\href{http://the-best-URL-in-the-world_without-a-number-sign}{URL without number ... 2 The Comprehensive Symbol Guide is your flexible friend concerning lookup of thousands of symbols: \documentclass{article} \begin{document}$\bot\bot\bot$\end{document} 1 Try using ntheorem and the nonumberplaintheorem style. The placement of endmarks is automatic (even if the environment ends up in displayed equations). Here is a possible code: \documentclass{article} \usepackage[utf8]{inputenc} \usepackage[T1]{fontenc} \usepackage{lmodern} \usepackage{lipsum} \usepackage{amsmath} \usepackage[thmmarks, amsmath, ... 0 Well, if I understand your question right, then you want to add a second author to the paper. Your given MWE is not complete, you missed for example command \maketitle to create the title sequence for the paper. Command \thanks includedes a footnote (with the asterix), so if you do not want it just comment is out (as I did in the following MWE) or just ... 0 If you were using this type of construction extensively you could define a notation such as $$\left.\sqrt{(a_k+(-1)^{p_k}(}\right\vert_{k=1}^n=\sqrt{(a_1+(-1)^{p_1}\sqrt{(a_2+(-1)^{p_2}\sqrt{(\cdots+\sqrt{a_n}}}}$$ MathJax is unable to handle the LaTeX so I have uploaded the image. 4 Add \usepackage{enumitem} to customize the labels. All the label syntax used below come from existing existing answers. To display a caret, preface it with \string. For the$, preface it with \ and for ], preface with \char. For the backslash, \textbackslash works here. \documentclass[10pt,a4paper]{article} \usepackage[utf8]{inputenc} \usepackage{enumitem} ...

Package amsmath uses \Longrightarrow to get the \Implies symbol. \Longrightarrow and \Longleftarrow are composed symbols with the standard fonts (unless a math font is used, which contain ready glyphs for the symbol). The arrow is taken from \Rightarrow and \Leftarrow, the equals sign = is used as prolongation, see macro \Relbar. At larger font sizes, the ...

You can find a font that has that Unicode symbol (see the list at http://www.fileformat.info/info/unicode/char/2314/fontsupport.htm), install it as a system font, load it using fontspec, and put that symbol directly in your .tex file. Compile with XeLaTeX or LuaLaTeX instead of pdfLaTeX. \documentclass{article} \usepackage{fontspec} \setmainfont{Cambria} ...

Ok, the problem was font Fontin doesn't support Croatian letters. I tried one that I was sure supports (like Andada-Regular) and it worked. Thank you very much. On the page https://www.fontsquirrel.com you can filter fonts by languages that they support and download them.

\usepackage{MnSymbol} I just searched The Comprehensive LaTeX Symbol List and found it.

Maybe the problem is the spacing when used in formulas? Look here: \documentclass{article} \usepackage[T1]{fontenc} \usepackage[utf8]{inputenc} \begin{document} a :- b $a :- b$ $a \mathop{:-} b$ $a \mathop{:\!-} b$ $a \mathop{:\!\!-} b$ %% suggested by Steven B. Seaglets $a \mathop{\vcenter{\hbox{$:$}}-} b$ \end{document}

This is an implementation using pict2e; the angle is 40 degrees. \documentclass{article} \usepackage{pict2e} \makeatletter \DeclareRobustCommand{\sector}{\mathord{\mathpalette\make@sector\relax}} \newcommand{\make@sector}[2]{% \settoheight{\unitlength}{$#1x$}% \begin{picture}(1,1.06) \linethickness{.08\unitlength} \moveto(0.5,0) \lineto(0.842,1) ...

There is a symbol from the fdsymbol package called \sector. Also, depending on your level of desperation, you might want to look through The Comprehensive LATEX Symbol List.

This seems to be a recently introduced bug in MikTeX, present at least in 2.9.5870. The example works after installing MikTeX 2.9.5550 (using the currently latest ProTeXT installer). A hack to make it work The example also works when you start from MikTeX 2.9.5550, and then update all packages except miktex-metafont-bin and miktex-mfware-bin. I did not try ...

A TikZ solution: The symbol is drawn by filling a path with three rectangles. Because of the even odd fill rule, the middle part remains empty/white. The height of the symbol is the height of uppercase letters. The outer "line width" is 0.4 pt, independent on the font size, the inner rectangle is set at 75% of the outer rectangle, dependent on the ...

I know of no font available with (pdf)latex that provides that shape, WHITE DIAMOND CONTAINING BLACK SMALL DIAMOND. On the other hand, it's not really difficult to build it. \documentclass{article} \usepackage{pict2e} \DeclareRobustCommand{\wdcbsd}{% \begingroup \setlength{\unitlength}{\fontcharht\font`T}% \begin{picture}(1,1) ...

U25C8 is the unicode no of this character (category Geometric shapes). Its name is ‘WHITE DIAMOND CONTAINING BLACK SMALL DIAMOND’. On this site, you can find a list of fonts which contain this symbol. You can use them with XeLaTeX or LuaLaTeX. Edit It seems the packages MnSymbol and fdsymbol each have a \diamonddiamond symbol which looks very much like ...

Symbol from Unicode font (LuaTeX or XeTeX) If LuaTeX or XeTeX is used with Unicode fonts, then the symbol can be used directly if the font supports this code point. Example for some fonts: \documentclass{article} \usepackage{fontspec} \begin{document} \newcommand*{\test}[1]{% #1:&\fontspec{#1}\symbol{"262D}\\% } \begin{tabular}{ll} \test{DejaVu Sans} ...
