The work of Fred
نویسندگان
چکیده
Summarizing Fred’s contributions to mathematics in a 1–hour talk, or for that matter in a single paper, is a daunting task. With nearly a hundred papers in print, and collaborations with no less than 48 authors, the sheer volume of his publication record makes trying to choose the appropriate highlights a difficult task. What makes it even harder is the variety of topics the work touches on. To all active topologists Fred Cohen is a very familiar name, and readers are likely to have a pretty good idea of the main topics his name is mostly associated with. For instance the study of configuration spaces and their applications, or his work on homotopy exponents with Moore and Neisendorfer. I will of course mention those in this article. However, as all who know him are aware, Fred’s interests are not limited to mainstream homotopy theory. Quite the contrary, he will never shy away from an opportunity to explore an unknown, possibly eccentric grounds. I will therefore attempt to explore some of the less known aspects of his work, which I find always interesting, and occasionally spectacular. This paper is not intended as a comprehensive summary of Fred’s mathematical contributions, but rather as a sampler of some of his many achievements.

Nitrogen is a crucial nutrient affecting plant growth and development and its addition to the soil (as chemical or organic form) influences plant growth characteristics. One experiment was conducted as a factorial based on RCBD with two Chrysanthemum cultivars (‘Fred’ and ‘Angel’( and two N-fertilizer sources [Urea (750 and 1500 g/ha and Nitroxin 7.5 and 15 L/ha] used as fertigation method besi...
متن کاملSolving Linear Fred Holm Fuzzy Integral Equations of the Second Kind by Modified Trapezoidal Method
One of the methods for solving definite integrals is modified trapezoid method, which is obtained by using Hermitian interpolation (see e.g. [12]). In this article, we have used modified trapezoid quadrature method and Generalized differential to solve the Fredholm fuzzy integral equations of the second kind. This method leads to solve fuzzy linear system. Finally the proposed method is illustr...
