[Tex/LaTex] Undefined Control Sequence Problem

sharelatex

I have the following code:

\title{Improvement of the Cascadic Multigrid Algorithm with a Gauss Seidel 
Smoother to Efficiently Compute the Fiedler Vector of a Graph Laplacian}
\author{Shivam Gandhi \href{email: shivam.jgandhi@gmail.com}
   \and \href{Tufts University Department of Mathematics}}
\date{November 2015}

However, it is returning the following error:

Undefined control sequence.
\@author ->Shivam Gandhi \href 
                               {email: shivam.jgandhi@gmail.com} \and \href ...
l.19 \maketitle

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

I am using ShareLaTeX for writing the paper, so it may be the compiler. Any ideas on how to fix this problem?

Thanks.

You may want something like this

\documentclass[a4paper]{article}
\usepackage{hyperref}
\begin{document}
\title{Improvement of the Cascadic Multigrid Algorithm with a Gauss Seidel 
Smoother to Efficiently Compute the Fiedler Vector of a Graph Laplacian}
\author{Shivam Gandhi
  \href{mailto:shivam.jgandhi@gmail.com}{shivam.jgandhi@gmail.com}
  \and \href{http://math.tufts.edu/}{Tufts University Department of Mathematics}}
\date{November 2015}
\maketitle
\end{document}

To expand on the excellent accepted answer: There are many alternatives to amsfonts for this symbol.

In the modern toolchain, there is no need to load any additional packages beyond unicode-math to get a ℝ that looks like the one from the early answer. It is already set up by default.

However, you can load the double-struck alphabet from any math font, or any display font that you’d rather use, with the range= option of \setmathfont. For example, to use Typoliner:

\documentclass[varwidth]{standalone}
\usepackage{unicode-math}

\defaultfontfeatures{Scale=MatchUppercase}

\setmathfont{Latin Modern Math}
\setmathfont[range=bb]{Typoliner-RW-Light.ttf}

\newcommand\setR{\symbb{R}}

\begin{document}
Let \(S \subset \setR\).
\end{document}

If you need compatibility with PDFLaTeX, or you would rather use a legacy NFSS font, you might want to use the mathalfa package to select your supplemental math alphabets.

[Tex/LaTex] ShareLatex – Error on import/include a .tex with algorithm2e into another .tex with prosa

I now am using the following workaround (i call it that way because it causes circumstances).

ever algorithm has its own tex file but without any preamble and without includes etc.
this way I cannot compile these files directly but need another tex using \input and all neccessary includes to compile this file
- this is cumbersome because I always need to change the tex for compiling when just changed a little on the pseudo-code

this way my code-tex is looking like this:

\begin{algorithm}
...
\end{algorithm

these "wrapper-tex" is looking like this:

\documentclass[12pt, letterpaper]{article}
\usepackage[utf8]{inputenc}
\usepackage{import}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage[linesnumbered,ruled]{algorithm2e}

\begin{document}

\import{Algo}{MyAlgo.tex}

\end{document}

For not getting the line pitch of the surrounding document I use \renewcommand before unsing input on the code and after it again to setting it back. When the code does not fit into the line latex display text, which actually occurs after the input, before the code itself (on the previous page if theres enough space left for text but not for code). I got it by adding a \newpage after the input of the code.

Using include does not show my pseudo code at all. My include that way looks like:

\begin{flushleft}

some text
...
again some text

\renewcommand{\baselinestretch}{1.0}

\input{Algo/MyAlog.tex}

\renewcommand{\baselinestretch}{1.5}


\newpage

againagainsometext
...
u know
\end{flushleft}
...

I had also problems because in the tex with my texts I defined 12pt fontsize while I didn at first on my code-wrapper. The pseudocode that way was enlarged after inputting it. Resizing it using recommendations of these Reduce pseudocode font size (not global) or othere did not help very much, I surrendered after over an hour trying so I reduced my pseudocode by dividing it into multiple/ separate algorithms and by deleting code commentary.
