ECC home Faculty of Science Masaryk University Eduard Èech Center Eduard Èech Center home Call for Applications Research positions Eduard Èech Center for Algebra and Geometry The Charles University in Prague the Masaryk University in Brno and the Mathematical Institute of the Academy of Sciences of the Czech Republic have jointly initiated a new centre supporting the development and exchange of ideas throughout the Czech and foreign universities and institutes, and providing a meeting place for leading experts in areas of Mathematics which combine geometrical and algebraic approaches. This project has been launched within the scheme "Centers of Excellence in Basic Research" , the Contracting Authority is the Czech Ministry for Youth, Education and Sport. Though the beginning is quite modest - about 6 regular post-doc positions for the entire period of 5 years, some budget for visitors, and some more support for seminars, workshops and conferences - this enterprise should be a starting point for a wider and more permanent institution. Eduard Cech has been chosen in the name of the Centre because it was just him who combined geometrical and algebraic thinking in his work and contributed amazingly to the evolution of all three institutions involved in the project at the same time.

Pravoúhlé simplexy a cyklické simplexy øe¹í speciální pøípady problému najít pøi dané souvislé a spojující síti na simplexu ten simplex, který má nejvìt¹í objem. Netupoúhlé simplexy (jejich ka¾dý vnitøní úhel je ostrý nebo pravý) úzce souvisejí s geometrickým znázornìním vá¾ených neorientovaných grafù, ale pøekvapivì i s odporovými elektrickými sítìmi. V teorii matic jsou jim ekvivalentní (symetrické) M-matice, známé z numerické lineární algebry. Souvislost s neorientovanými vá¾enými grafy prostøednictvím tzv. Laplaceových matic umo¾òuje grafové pojmy pøevést na pojmy maticové (napø. algebraická souvislost).

It is named for the mathematician Construction Let X be a topological space with open cover U U I , a countable ordered set . We will simplify notation by writing intersections as U U U , and so on for higher intersections. For every intersection U there are n + 1 inclusions defined as follows: i U U i skips the i th open set. We now define the cochain groups for this cohomology. Let F be a presheaf . The 0-cochains on U with values in F are functions assigning an element of F U ) to every open set U . Using the properties of products , we may write C U F I F U Then we define the 1-cochains to be elements of C U F F U and so on, so that C i U F F U Next, the
