### Maltsiniotis's first conjecture for K_1 , by Fernando Muro

We show that K_1 of an exact category agrees with K_1 of the associated
triangulated derivator. More generally we show that K_1 of a Waldhausen
category with cylinders and a saturated class of weak equivalences coincides
with K_1 of the associated right pointed derivator.
