متن کاملTranslated Whitney and r-Whitney Numbers: A Combinatorial Approach
Using a combinatorial approach, we introduce the translated Whitney numbers. This seems to be more natural than to write a product of anarithmetical progression in terms of a power variable and conversely. We also extend our ideas to translated r-Whitney numbers of both kinds and to translated Whitney-Lah numbers.
متن کاملVolume, Density and Whitney Conditions
This paper studies the variation of the volume of a subanalytic family of sets. More precisely we are interested in the variation of the density. We prove that the density is continuous along a stratum of a Whitney subanalytic stratification and locally lipschitzian when the stratification satisfies the Kuo-Verdier condition. This problem had been studied by Comte in [C].
متن کاملUV radiation protection by handheld umbrellas.
T he handheld umbrella (HU) is a commonly employed method of sun protection by women in many countries in Asia (45% in China) and the Middle East. In Turkey, hats and umbrellas were found to be the most common photoprotection accessories. The HU was standard outdoor attire for women of the 18th and 19th centuries in the United States. In the next century, sunscreen, hats, and sun-protective clo...
متن کاملWhitney algebras and Letterplace superalgebras
I’ll give an outline of the theory of Whitney algebras of a matroid, with the notions of geometric product and the excahnge relations, I’ll give the letterplace superalgebra coding of these algebras, and I’ll show how this coding allows to get the exchange relations directly from the superstraightening laws. I’ll not speak about the Lax Hopf algebra structure of Whitney algebras. All this is pa...
