نویسنده
چکیده
It is, with heavy hearts, that we report that our friend and mentor, Theodore J. Rivlin, died on July 22, 2006, in Croton-on-Hudson, New York, just weeks before his 80th birthday. He had suffered from Alzheimer’s disease in his final years. Ted was an associate editor of Journal of Approximation Theory from its inception in 1968. Ted was born on September 11, 1926, in Brooklyn, New York. He received his undergraduate degree at Brooklyn College in 1948. After serving for 18 months with the U.S. Army Air Force, he continued his mathematical education at Harvard University, where he received his Ph.D. in 1953 under the supervision of Joseph L. Walsh. His thesis was concerned with the phenomenon of overconvergence of power series.

A Family of Gauss - Kronrod Quadrature Formulae
We show, for each n > 1, that the (2ra + l)-point Kronrod extension of the n-point Gaussian quadrature formula for the measure do-^t) = (1 + 7)2(1 t2)^2dt/((l + -y)2 47t2), -K -y < 1, has the properties that its n + 1 Kronrod nodes interlace with the n Gauss nodes and all its 2ra + 1 weights are positive. We also produce explicit formulae for the weights.
متن کاملEffect of magnetic field on thermal instability of a rotating Rivlin-Ericksen viscoelastic fluid
The thermal instability of a rotating Rivlin-Ericksen viscoelastic fluid in the presence of uniform vertical magnetic field is considered. For the case of stationary convection, Rivlin-Ericksen viscoelastic fluid behaves like a Newtonian fluid. It is found that rotation has a stabilizing effect, whereas the magnetic field has both stabilizing and destabilizing effects. Graphs have been plotted ...
