Exceptional graphs with smallest eigenvalue -2 and related problems
This paper summarizes the known results on graphs with smallest eigenvalue around -2, and completes the theory by proving a number of new results, giving comprehensive tables of the finitely many exceptions, and posing some new problems. Then the theory is applied to characterize a class of distance-regular graphs of large diameter by their intersection array
Ein Narr, Ein Weiser und viele Tiere: Alte Fabeln, neu erzählt
I enjoy this spirited book. Not quite as sardonic as Bierce, it is in the same direction. FC offers a good beginning taste of the good stuff that goes on here. The cheese hits the fox right in the nose, he breaks into tears, and he finally runs wailing from the scene. The crow cannot understand what has just happened, but he eats the cheese. As the illustration shows nicely at the end of LM, the lion fulfills the mouse's wish never to have to tremble again -- by eating him! In MSA, the ass sells himself and takes a trip with the profits! The foxes do cut off their tails, and then they mock the fox who found the first tail in a trap: Tail is out of fashion, and he has two of them! The vintner comes upon the complaining fox in FG, tries to hit him but instead hits the vine. Grapes fall, and the fox makes off with them. The cat does end up eating the bat and then says Tastes just like mouse! The sons of the dying father are still digging in the vineyard as the book closes. Good fun, including the spirited black-and-white illustrations.This is a hardbound book (hard cover)Language note: GermanFrans Haacke
