Linear change of coordinates preserving a certain property

Click For Summary
SUMMARY

A linear change of coordinates does preserve the property of complete intersection for a set of homogeneous polynomials in a polynomial ring. Specifically, when applying a linear transformation to a set of homogeneous polynomials {f_1,..., f_k} in C[x_1,...,x_M], if the resulting variety defined by {h_1,...,h_k} is a complete intersection, then the original set {f_1,...,f_k} must also form a complete intersection. This conclusion is established based on the properties of polynomial rings and the nature of homogeneous polynomials.

Doesn't a linear change of coordinates preserve complete intersection for a set of homogeneous polynomials, all of the same degree, in a polynomial ring?

That is, apply a change of coordinates to a set of homogeneous polynomials {f_1,... f_k} in C[x_1,...,x_M] to obtain {h_1,..., h_k}. Suppose now that the variety cut out by {h_1,...,h_k} is a complete intersection. Doesn't this imply that the original set of generators {f_1,... f_k} formed a complete intersection?

This seems very plausible.
