摘要：Let $a$, $b$ be two fixed positive constants. A function $gin L^2(R)$ is called a mother Weyl-Heisenberg frame wavelet for $(a,b)$ if $g$ generates a frame for $L^2(R)$ under modulates by $b$ and translates by $a$, i.e., ${e^{imbt}g(t-na}_{m,nin Z}$ is a frame for $L^2（R)$. In this talk，we establish a connection between mother Weyl-Heisenberg frame wavelets of certain special forms and certain strongly positive definite quadratic forms of infinite dimension. Some examples of application in matrix algebra are provided.
