The classical tale - of the hypergeometric capabilities, the configuration house of four issues at the projective line, elliptic curves, elliptic modular capabilities and the theta features - now evolves, during this e-book, to the tale of hypergeometric funktions in four variables, the configuration house of 6 issues within the projective aircraft, K3 surfaces, theta capabilities in four variables.
this contemporary conception has been validated by way of the writer and his collaborators within the 1990's; additional improvement to diversified points is expected.
It leads the reader to a desirable four-dimensional world.
the writer tells the tale casually and visually in a undeniable language, beginning shape ordinary point reminiscent of equivalence family, the exponential functionality, ... Undergraduate scholars can be capable of benefit from the text.
