THE GENERALIZED WIELANDT INEQUALITY IN INNER PRODUCT SPACES
M. Lin; G. Sinnamon
A new inequality between angles in inner product spaces is formulated and
proved. It leads directly to a concise statement and proof of the generalized Wielandt
inequality, including a simple description of all cases of equality. As a consequence,
several recent results in matrix analysis and inner product spaces are improved.

operator equation is suggested.

ON THE BOUNDEDNESS OF SOME CLASSES OF INTEGRAL OPERATORS IN WEIGHTED LEBESGUE SPACES
L.S. Arendarenko; R. Oinarov; L.-E. Persson
Some new Hardy-type inequalities for Hardy-Volterra integral operators
are proved and discussed. The case 1 < q < p < 1 is considered and the involved
kernels satisfy conditions, which are less restrictive than the usual Oinarov condition.
