+\title{Papers implemented in \textsc{libigl}}
+\author{Alec Jacobson}
+\date{4 April 2014}
+
+\begin{document}
+This document serves as a companion reference to better list the references to
+scientific articles implemented within \textsc{libigl}. It will no doubt be
+incomplete.
+
+\paragraph{\texttt{cotmatrix}, \texttt{massmatrix}}
+build discrete operators on triangle and tetrahedral meshes. 
+\cite{Pinkall:1993:CDM,meyer03ddo,Jacobson:THESIS:2013}. 
+
+\paragraph{\texttt{harmonic}} solves a Laplace problem (equivalently
+minimizes the Dirichlet energy) with some simple boundary conditions
+\cite{HarmonicCoodinates07}. There's also an option to solve
+``higher order Laplace problems'' (bi-Laplace, tri-Laplace, etc.)
+\cite{Botsch:2004:AIF,sorkine04lsm,Jacobson:MixedFEM:2010}.
+
+\paragraph{\texttt{bbw/}} implements ``bounded biharmonic
+weights'' \cite{Jacobson:BBW:2011}.
+
+\paragraph{\texttt{svd3x3/arap}} is a generalized implementation
+for solving ``as-rigid-as-possible'' (ARAP) mesh deformation or parameterization
+problems \cite{ARAP_modeling:2007,Liu:2008:ALA,Chao:2010:ASG}.
+
+\paragraph{\texttt{svd3x3/arap\_dof}} implements ``FAST'',
+which is simultaneously a reduced form of ARAP and a method for automatically
+choosing skinning transformations \cite{Jacobson:FAST:2012}.
+
+\paragraph{\texttt{dqs}} implements ``Dual quaternion skinning''
+\cite{Kavan:2008:GSW}.
+
+\paragraph{\texttt{lbs}} implements ``linear blend skinning'', also known as
+``skeletal subspace deformation'', or ``enveloping''. This technique is often
+attributed to \cite{Magnenat-Thalmann:1988:JLD}.
