✦ Synopsis

dedicated to professor w. t. tutte on the occasion of his eightieth birthday

We present several new polynomial identities associated with matroids and geometric lattices and relate them to formulas for the characteristic polynomial and the Tutte polynomial. The identities imply a formula for the Le^numbers of complex hyperplane arrangements.

Red and green visual pigment genes were analyzed in color-normal Japanese males. DNA from 121 males was subjected to PCR-amplification for the promoter and exon 5 of these genes, and the products were sequenced with a PRISM 310 genetic analyzer (dye terminator). The number of visual pigment genes in

Relations among endoscopy liftings of automorphic forms, poles of L-functions, and nonvanishing of certain periods of automorphic forms have long been expected, although they have not been formulated, even conjecturally. We take a first step toward considering the relations by formulating our conjec
