Dear categoricist,
Let I be the following small category :
a a a
--------> --------> -------->
.. n n-1 n-2 ...... 0
--------> --------> -------->
b b b
with the relations a o a = a o b and b o a = b o b.
Consider the category C of functors from I to the category of
K-modules. How could we characterize the projective objects of C ?
Any idea, any reference, is welcome.
