On Matrix Rigidity and the Complexity of Linear Forms

Electron. Colloquium Comput. Complex., 2005
The rigidity function of a matrix is defined as the minimum number of its entries that need to be changed in order to reduce the rank of the matrix to below a given parameter. Proving a strong enough lower bound on the rigidity of a matrix implies a nontrivial lower bound on the complexity of any linear circuit computing the set of linear forms ...
