We propose the following conjecture: For every fixed alpha is an element of [0, 1/3), each graph of minimum degree at least (1 + alpha)k/2 and maximum degree at least 2(1 - alpha)k contains each tree with k edges as a ...

A quantitative study of metazoan meiofauna was carried out at continental shelf and slope stations affected by the oxygen-minimum zone in the eastern South Pacific off Chile. Densities of meiobenthos at the investigated ...

Let p be a prime number. A formula for the minimum absolute value of the discriminant of all Abelian extensions of Q of degree p(2) is given in terms of p.

We study W1,p Lagrange interpolation error estimates for general quadrilateral Qk finite elements with k≥2. For the most standard case of p=2 it turns out that the constant C involved in the error estimate can be bounded ...
