Frobenius Splittings
Frobenius splittings were introduced by V. B. Mehta and A. Ramanathan in [6] and refined further by S. Ramanan and Ramanathan in [9]. Frobenius splittings have proven to be a amazingly effective when they apply. Proofs involving Frobenius splittings tend to be very efficient. Other methods usually require a much more detailed knowledge of the object under study. For instance, while showing that...
متن کاملHyperfine splittings in bottomonium
A universal description of the hyperfine splittings (HFS) in bottomonium and the Bq (q 1⁄4 n, s, c) mesons is obtained with a universal strong coupling constant sð Þ 1⁄4 0:310 in a spin-spin potential. Other characteristics are calculated within the field correlator method, taking the freezing value of the strong coupling independent of nf. The HFS MðB Þ MðBÞ 1⁄4 45:5ð1Þ MeV, MðB sÞ MðBsÞ 1⁄4 4...
متن کاملRandom Heegaard splittings
Consider a random walk on the mapping class group, and let wn be the location of the random walk at time n. A random Heegaard splitting M(wn) is a 3-manifold obtained by using wn as the gluing map between two handlebodies. We show that the joint distribution of (wn, w −1 n ) is asymptotically independent, and converges to the product of the harmonic and reflected harmonic measures defined by th...
متن کاملEntropy Flux - Splittings
A general framework is proposed for the derivation and analysis of ux-splittings and the corresponding ux-splitting schemes for systems of conservation laws endowed with a strictly convex entropy. The approach leads to several new properties of the existing ux-splittings and to a method for the construction of entropy ux-splittings for general situations. A large family of genuine entropy ux-sp...
متن کاملIntegral Kašin Splittings
For x ∈ R and p ≥ 1 put ‖x‖p := (n−1 ∑ |xi|). An orthogonal direct sum decomposition R = E ⊕ E⊥ where dimE = k and sup0 6=x∈E∪E⊥ ‖x‖2 / ‖x‖1 ≤ C is called here a (k,C)-splitting. By a theorem of Kašin there exists C > 0 such that (k,C)-splittings exist for all k, and by the volume ratio method of Szarek one can take C = 32eπ. All proofs of existence of (k,C)-splittings heretofore given are nonc...
