Stroh assumes that every **reducible** seminvariant can in this way be reduced.

Borchers predicted that, at the high temperatures available with the electric furnace, every oxide would prove to be **reducible** by the action of carbon, and this prediction has in most instances been justified.

Although Hippocrates could not determine the proportionals, his statement of the problem in this form was a great advance, for it was perceived that the problem of trisecting an angle was **reducible** to a similar form which, in the language of algebraic geometry, is to solve geometrically a cubic equation.

The work demanded seems **reducible** to a virtually negligible portion of a life.

When 0=4 it is clear that no form, whose partition contains a part 3, can be reduced; but every form, whose partition is composed of the parts 4 and 2, is by elementary algebra **reducible** by means of perpetuants of degree 2.
