3. Department <strong>of</strong> Algebra: The Department <strong>of</strong> Algebra was organized and for a long<br />

time headed by B. N. Delone. Due <strong>to</strong> his influence, <strong>the</strong> Department is still active in<br />

<strong>the</strong> <strong>the</strong>ory <strong>of</strong> algebraic numbers and diophantine equations. Since 1960, <strong>the</strong> Head<br />

<strong>of</strong> Department has been I. R. Shafarevich. Since about <strong>the</strong> same time, <strong>the</strong><br />

Department became active in algebraic geometry. The Department staff includes: A.<br />

I. Kostrikin, A. N. Parshin, A. N. Turin, V.A.Kolyvagin, V. N. Nikulin, S. A.<br />

Stepanov. At <strong>the</strong> Department, A. I. Malte, S. A. Chunikhin, I. M. Gel'fand, S. P.<br />

Demushkin, S. P. Novikov, A. I. Lapin, and M. M. Kapranovalso worked at<br />

different times.<br />

There are six main <strong>to</strong>pics actively developed in <strong>the</strong> Department, namely:<br />

The arithmetic <strong>of</strong> fields <strong>of</strong> algebraic numbers. The most famous results obtained<br />

here are <strong>the</strong> solution <strong>of</strong> <strong>the</strong> inverse problem <strong>of</strong> Galois <strong>the</strong>ory for solvable groups,<br />

<strong>the</strong> investigation <strong>of</strong> <strong>the</strong> Galois groups <strong>of</strong> fields <strong>of</strong> p-adic numbers, <strong>the</strong> solution <strong>of</strong><br />

<strong>the</strong> problem <strong>of</strong> class field <strong>to</strong>wer.<br />

The <strong>the</strong>ory <strong>of</strong> Lie groups and algebras. At <strong>the</strong> time when A. I. Maltsev worked at<br />

<strong>the</strong> Department he obtained results on semi-simple subgroups <strong>of</strong> semi-simple Lee<br />

groups, <strong>the</strong> <strong>the</strong>ory <strong>of</strong> nimanifolds <strong>of</strong> <strong>the</strong> Maltsev completions <strong>of</strong> groups. When I.<br />

M. Gel'fand worked at <strong>the</strong> Department, <strong>the</strong> Gelfand-Naimark <strong>the</strong>ory <strong>of</strong> infinite<br />

dimensional representations <strong>of</strong> classical Lee groups was developed.<br />

The <strong>the</strong>ory <strong>of</strong> finite groups and modular Lee algebras. The limited Bernside<br />

problem was solved and <strong>the</strong> basis <strong>of</strong> <strong>the</strong> <strong>the</strong>ory <strong>of</strong> simple Lee p-algebras was<br />

constructed.<br />

The arithmetic <strong>of</strong> algebraic manifolds: <strong>the</strong> <strong>the</strong>ory <strong>of</strong> elliptic curves, <strong>the</strong><br />

multidimensional class field, <strong>the</strong> arithmetic <strong>of</strong> algebraic and arithmetic surfaces,<br />

``<strong>the</strong> Arakelov geometry''.<br />

Algebraic geometry: <strong>the</strong> solution <strong>of</strong> <strong>the</strong> Luroth problem, <strong>the</strong> <strong>the</strong>ory <strong>of</strong> K3 type algebraic<br />

surfaces.<br />

Problems <strong>of</strong> ma<strong>the</strong>matical physics connected with algebraic geometry: instant<br />

on <strong>the</strong>ory, gauge fields <strong>the</strong>ory, super-geometry. Of course some investigation do<br />

not fit in <strong>the</strong> outlined directions. Recently also new directions <strong>of</strong> investigations<br />

appeared: problems <strong>of</strong> homological algebra; <strong>the</strong> classification <strong>of</strong> multidimensional<br />

algebraic manifolds; <strong>the</strong> <strong>the</strong>ory <strong>of</strong> nilpotent algebras; and <strong>the</strong> study <strong>of</strong> <strong>the</strong> Galois<br />

groups <strong>of</strong> <strong>the</strong> algebraic closure <strong>of</strong> fields <strong>of</strong> a finite type.<br />

Many young ma<strong>the</strong>maticians have been trained at <strong>the</strong> Department. The present members <strong>of</strong><br />

<strong>the</strong> Department have advised more <strong>the</strong>n 75 candidates and 30 doc<strong>to</strong>rs <strong>of</strong> Physical-<br />

Ma<strong>the</strong>matical sciences.<br />

4. Department <strong>of</strong> Geometry and Topology: The Department <strong>of</strong> Geometry and<br />

Topology at <strong>the</strong> Ma<strong>the</strong>matical Institute was organized in 1939 and <strong>the</strong> first Head <strong>of</strong><br />

Department was L. S. Pontryagin. P. S. Aleksandrov joined <strong>the</strong> Department at that<br />

time.<br />

Topology became an independent branch <strong>of</strong> science and <strong>the</strong> organization <strong>of</strong> <strong>the</strong> Department<br />

was a reflection <strong>of</strong> it. The main <strong>to</strong>pics investigated at <strong>the</strong> Department were<br />

differential <strong>to</strong>pology (L. S. Pontryagin) and general algebraic <strong>to</strong>pology (P. S.<br />

Aleksandrov). Even though <strong>the</strong> Department was ra<strong>the</strong>r small, investigations in all <strong>of</strong><br />

<strong>the</strong> main directions <strong>of</strong> <strong>the</strong> development <strong>of</strong> <strong>to</strong>pology were carried on.<br />

After <strong>the</strong> War, a large number <strong>of</strong> talented ma<strong>the</strong>maticians joined <strong>the</strong> Department. They were<br />

L. V. Keldysh, (Keldish) who actively studied problems <strong>of</strong> geometric <strong>to</strong>pology,<br />

and L. S. Pontryagin's and P. S. Aleksandrov's students N. A. Berikashvili, V.<br />

G. Boltyanskii, R. V. Gamkrelidze, M. M. Postnikov, K. A. Sitnikov . At <strong>the</strong><br />
