By L. A. Bokut’, K. A. Zhevlakov, E. N. Kuz’min (auth.), R. V. Gamkrelidze (eds.)

This quantity comprises 5 evaluation articles, 3 within the Al gebra half and within the Geometry half, surveying the fields of ring conception, modules, and lattice idea within the former, and people of imperative geometry and differential-geometric equipment within the calculus of diversifications within the latter. The literature coated is basically that released in 1965-1968. v CONTENTS ALGEBRA RING conception L. A. Bokut', ok. A. Zhevlakov, and E. N. Kuz'min § 1.
