Some Group Theory Problems
This is a survey of some problems in geometric group theory which I find interesting. The problems are from different areas of group theory. Each section is devoted to problems in one area. It contains an introduction where I give some necessary definitions and motivations, problems and some discussions of them. For each problem, I try to mention the author. If the author is not given, the prob...
متن کاملSome Problems of Spectral Theory
Also compact operators of scalar type in any Banach can be so expressed, provided, the sum (1) is allowed to be countably infinite. It is perhaps less often noted that any operator of scalar type can be expressed in the form (1), with the index j running over all positive integers. But, in general, the projections P. cannot be chosen pair-wise J disjoint, that is, the product of any distinct pa...

متن کاملSome Problems in Number Theory
A k = max(p,+ t p,), k < p, < p, + , < 2k . In fact I cannot even disprove f(k) = Ak for all sufficiently large k, though it seems likely that f(k) > Ak for all large k. A well known theorem of Pólya and Störmer states that if u > uo(k) then u(u + 1) always contains a prime factor greater than k, thusf(k) can be determined in a finite number of steps, and an explicit bound has been given by Leh...
