Nonvanishing derivatives and the MacLane class A
نویسندگان
چکیده
Let k ≥ 2 and let f be meromorphic in the unit disc ∆, such that f(z)f (k)(z) 6= 0 for all z ∈ ∆ and the poles of f in ∆ have bounded multiplicities. Then f has asymptotic values on a dense subset of ∂∆. MSC: 30D40, 30D35.

ON THE CAPACITY OF EILENBERG-MACLANE AND MOORE SPACES
K. Borsuk in 1979, at the Topological Conference in Moscow, introduced concept of the capacity of a compactum and asked some questions concerning properties of the capacity ofcompacta. In this paper, we give partial positive answers to three of these questions in some cases. In fact, by describing spaces homotopy dominated by Moore and Eilenberg-MacLane spaces, the capacities of a Moore space $...
متن کاملQuantitative Nonvanishing of L-series Associated to Canonical Hecke Characters
We prove quantitative nonvanishing theorems for central values and central derivatives of L–series associated to canonical Hecke characters of imaginary quadratic fields. These results have applications to the study of Chow groups of Kuga-Sato varieties. Some key ingredients in the proofs are bounds for `-torsion in class groups obtained recently by Ellenberg and Venkatesh [EV], and subconvexit...
متن کاملPharmacological Profile of Oxazine and its Derivatives: A Mini Review
Oxazine derivatives are significant class of heterocycle compounds, which has involved much synthetic attention due to their extensive variety of pharmacological activities. Oxazine is a heterocyclic compound can be formally derived from benzene, and its reduction products, by suitable substitution of carbon (and hydrogen) atoms by nitrogen and oxygen. In the last few years oxazine derivatives ...
