Calculated Murder.

Wouldn't it be nice, Leonard Rosen asks in his first novel, ALL CRY CHAOS (Permanent Press, $29), if the broken world we live in could be mended by the application of some universal mathematical formula? James Fenster, a Harvard professor who's in Amsterdam to deliver a paper before the World Trade Organization, has been working on that very thing. But before he can deliver his remarks on ''The Mathematical Inevitability of a One-World Economy,'' a bomb charged with rocket fuel delivers a surgical strike on his hotel room. Henri Poincare, a veteran Interpol agent, seems the ideal man to investigate the murder, since he's the great-grandson of the mathematician Jules Henri Poincare and something of a brain himself. ''So who kills a mathematician, other than another mathematician?'' his young protege wants to know. Poincare turns up some promising candidates, one of them a financier who funded some of Fenster's work in hopes of applying it to the stock market, another a brilliant economist turned political provocateur. There's even a group of religious fundamentalists intent on creating the chaos that would hasten the Second Coming. With the exception of the victim's former fiancee, whose suspicious behavior has also made her a person of interest, these suspects are all sold on the idea that ''human behavior can be modeled mathematically, just as any complex, dynamic system in nature can be modeled.''
