  We construct smooth concordance invariants of knots which take the form of
piecewise linear maps from [0,1] to R, one for each n greater than or equal to
2. These invariants arise from sl(n) knot cohomology. We verify some properties
which are analogous to those of the invariant Upsilon (which arises from knot
Floer homology), and some which differ. We make some explicit computations and
give some topological applications. Further to this, we define a concordance
invariant from equivariant sl(n) knot cohomology which subsumes many known
concordance invariants arising from quantum knot cohomologies.
