Query: M-tensors and The Positive Definiteness of a Multivariate Form   We study M-tensors and various properties of M-tensors are given. Specially,
we show that the smallest real eigenvalue of M-tensor is positive corresponding
to a nonnegative eigenvector. We propose an algorithm to find the smallest
positive eigenvalue and then apply the property to study the positive
definiteness of a multivariate form.
