چکیده

We show that assuming lower bounds on the Ricci curvature and injectivity radius absolute value of certain characteristic numbers a Riemannian manifold, including all Pontryagin Chern numbers, is bounded proportionally to volume. The proof relies Chern–Weil theory applied connection constructed from Euclidean connections charts in which metric tensor harmonic has Hölder norm. generalize this theorem Gromov–Hausdorff closed class rough manifolds defined terms regularity. Assuming an additional upper bound, we also Euler Additionally, remark volume comparison for Betti with bound sectional curvature. It consequence result by Bowen.

A Tauberian theorem for $(C,1,1)$ summable double sequences of fuzzy numbers

In this paper,  we determine necessary and sufficient Tauberian conditions under which convergence in Pringsheim's sense of a double sequence of fuzzy numbers follows from its $(C,1,1)$ summability. These conditions are satisfied if the double sequence of fuzzy numbers is slowly oscillating in different senses. We also construct some interesting double sequences of fuzzy numbers.

A FUZZY COMPARISON METHOD FOR PARTICULAR FUZZY NUMBERS

In a previous work, we introduced particular fuzzy numbers anddiscussed some of their properties. In this paper we use the comparison methodintroduced by Dorohonceanu and Marin[5] to compare between these fuzzynumbers.

Divisibility of characteristic numbers

We use homotopy theory to define certain rational coefficients characteristic numbers with integral values, depending on a given prime number q and positive integer t . We prove the first nontrivial degree formula and use it to show that existence of morphisms between algebraic varieties for which these numbers are not divisible by q give information on the degree of such morphisms or on zero c...

On Leibniz’ Characteristic Numbers

In 1679, Leibniz wrote nine manuscripts on three different arithmetical models of Aristotelian logic. This was a part of his project of a “calculus universalis”. First we show the precise relations of these three models to each other by presenting three criteria which serve the purpose of classifying models of Aristotelian logic. This facilitates the understanding of Leibniz’ constructions. Our...

Barycentric Characteristic Numbers

If G is the category of finite simple graphs G = (V,E), the linear space V of valuations on G has a basis given by the f-numbers vk(G) counting complete subgraphs Kk+1 in G. The barycentric refinement G1 of G ∈ G is the graph with Kl subgraphs as vertex set where new vertices a 6= b are connected if a ⊂ b or b ⊂ a. Under refinement, the clique data transform as ~v → A~v with the upper triangula...
