Abstract
Let (Formula presented.) be a partition of (Formula presented.). Consider the variety (Formula presented.) , parameterizing forms (Formula presented.) which are the product of (Formula presented.) forms (Formula presented.) , with (Formula presented.). We study the secant line variety (Formula presented.) , and we determine, for all (Formula presented.) and (Formula presented.) , whether or not such a secant variety is defective. Defectivity occurs in infinitely many “unbalanced” cases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
