<div align="left"><b><b><font color="#ff0000">Abstract:</font></b></b><font
color="#ff0000"><font color="#000000"> Toric varieties are
interesting geometric objects lying on the crossroad of
algebra, geometry and combinatorics containing a dense
torus which is an algebraic group acting on the toric
variety. Many champion codes obtained from toric
varieties appeared in the literature.<br>
<br>
The simplest examples of toric varieties include
classical and weighted projective spaces. Parameters of
linear codes obtained by evaluating rational functions
on a projective torus are computed in 2011 by Sarmiento,
Vaz Pinto and Villarreal. This idea is transferred to
weighted projective tori and some parameters are
computed in 2015 by Dias and Neves.<br>
<br>
The purpose of this talk is to introduce some linear
codes on toric varieties. We focus on codes obtained
from certain subgroups of the weighted projective torus
over a finite field, and to share some formulas for
their parameters in some cases. We restrict to two
dimensional case to obtain more explicit formula for the
minimum distance of the code on the weighted projective
torus T(1,1,a) over F_q.<br>
