My research interest is in tensor computation. Tensors are higher-order generalizations of vectors and matrices.
In particular, a scalar is a zeroth-order tensor, a vector is a first-order tensor, and a matrix is a second-order tensor.
Research interests:
- Tensor theory
- Generalized inverses of tensors and their applications
- Structured tensors
- Hypergraphs
