% This is a template for abstracts
% for Spring School. Please rename the file
% according to your real surname.
%
% Try not to create much special tex definitions.
%
% The text should be an extended abstract. It will be used
% as a handout during the presentation and then it will
% be recycled to "Sbornicek" (thin book about Spring School).
% So don't be shy and write more than 10 lines :-)
%
% If you want you may use \section to make sections in the abstract. But
% try to avoid \subsection - We do not have any formating macro for it anyway.
%
% If you wish to use references please do not use \cite and automatic
% reference creation. Instead write directly [1] to the text and create 
% The references by hand. Please include references only if they are really 
% important. Do not copy all references from an article you are talking about.
% Note that you do not have to write any references to your abstract at all if
% do not want to.
%
% If you are unsure how the extended abstract should look you may find
% some inspiration in "sbornicek" from recent years, e.g.
% http://kam.mff.cuni.cz/~kamserie/serie/clanky/2006/s773.pdf
% After reading your extended abstract one should understand
% what is your talk about and have some idea what is going on.
% It is not expected that all proofs will be present.
% 
% If you have any suggestions/comments/patches/hotfixes/dirty jokes please send them
% to Vojta: tumav (at) atrey.karlin.mff.cuni.cz
% 
%
% Version: 1.1
%     - added package amssymb
%     - square at the end of the proof

\section{Introduction}

Some text about the paper. 
quaeram te, domine, invocans te, et invocem te credens in te: praedicatus enim es nobis.
invocat te, domine, fides mea, quam dedisti mihi, quam inspirasti mihi per humanitatem 
filii tui, per ministerium praedicatoris tui.

Second paragraph. Hope you like it.

\section{More formally}

\begin{definition}
Magnus es, domine, et laudabilis valde: magna virtus tua, et sapientiae tuae non est numerus. 
et laudare te vult homo, aliqua portio creaturae tuae, et homo circumferens mortalitem suam.
\end{definition}

\begin{lemma}
Sed quis te invocat nesciens te? aliud enim pro alio potest invocare nesciens. 
an potius invocaris, ut sciaris? quomodo autem invocabunt, in quem non crediderunt.
\end{lemma}

\begin{theorem}
The very nice result.
\end{theorem}

\begin{proof}
A sketch of proof if You like. Maybe [1] is used here.
\end{proof}

\begin{corollary}
Some more talking about the article.
\end{corollary}

And even more talking about the article. 

\begin{conjecture}
Maybe this holds.
\end{conjecture}
