As a part of the medical job in reference to the seventieth birthday of the Adam Mickiewicz college in Poznan, a global convention on algebraic topology used to be held. within the ensuing lawsuits quantity, the emphasis is on colossal survey papers, a few offered on the convention, a few written accordingly.

An Introduction to Differential Manifolds

This ebook is an advent to differential manifolds. It provides good preliminaries for extra complex issues: Riemannian manifolds, differential topology, Lie thought. It presupposes little historical past: the reader is barely anticipated to grasp uncomplicated differential calculus, and a bit point-set topology.

Partial Differential Equations. Basic theory

Arithmetic is taking part in an ever extra vital function within the actual and organic sciences, frightening a blurring of limitations among clinical disciplines and a resurgence of curiosity within the modem as weIl because the classical ideas of utilized arithmetic. This renewal of curiosity, either in study and educating, has resulted in the institution of the sequence: Texts in utilized arithmetic (TAM).

The Hilton symposium, 1993: Topics in topology and group theory

This quantity provides a cross-section of recent advancements in algebraic topology. the most component comprises survey articles compatible for complex graduate scholars and execs pursuing study during this sector. an exceptional number of issues are coated, lots of that are of curiosity to researchers operating in different components of arithmetic.
