Explicit Growth and Expansion for Sl2

نویسنده

  • EMMANUEL KOWALSKI
چکیده

We give explicit versions of Helfgott’s Growth Theorem for SL2, as well as of the Bourgain-Gamburd argument for expansion of Cayley graphs modulo primes of subgroups of SL2(Z) which are Zariski-dense in SL2.

Recurrences and explicit formulae for the expansion and connection coefficients in series of the product of two classical discrete orthogonal polynomials

Suppose that for an arbitrary function $f(x,y)$ of two discrete variables, we have the formal expansions. [f(x,y)=sumlimits_{m,n=0}^{infty }a_{m,n},P_{m}(x)P_{n}(y),] $$‎ ‎x^{m}P_{j}(x)=sumlimits_{n=0}^{2m}a_{m,,n}(j)P_{j+m-n}(x)‎,$$ ‎we find the coefficients $b_{i,j}^{(p,q,ell‎ ,‎,r)}$ in the expansion‎ $$‎ ‎x^{ell }y^{r},nabla _{x}^{p}nabla _{y}^{q},f(x,y)=x^{ell‎ ‎}y^{r}f^{(p,q)}(x,y) =sumli...

Expanded effector memory T-lymphocytes in DBA/2 mice do not inhibit the growth of SL2 tumours.

BACKGROUND The aim of this study was to analyse changes in levels of memory T-lymphocytes during growth of SL2 tumours in DBA/2 mice and to evaluate whether these lymphocytes may have an inhibitory effect on tumour growth. MATERIALS AND METHODS Percentages of naïve (CD8+CD44lowCD62L+), central memory (CD8+CD44high CD62L+) and effector memory (CD8+CD44highCD62L-) lymphocytes in the CD8+ subset...

Explicit geodesic flow-invariant distributions using SL2(ℝ)-representation ladders

An explicit construction of a geodesic flow-invariant distribution lying in the discrete series of weight 2k isotopic component is found, using techniques from representation theory of SL2(R). It is found that the distribution represents an AC measure on the unit tangent bundle of the hyperbolic plane minus an explicit singular set. Finally, via an averaging argument, a geodesic flow-invariant ...

Generating function of correlators in the sl2 Gaudin model

For the sl2 Gaudin model (degenerated quantum integrable XXX spin chain) an exponential generating function of correlators is calculated explicitely. The calculation relies on the Gauss decomposition for the SL2 loop group. From the generating function a new explicit expression for the correlators is derived from which the determinant formulas for the norms of Bethe eigenfunctions due to Richar...

Character Degrees of Extensions of PSL2(q) and SL2(q)

Denote by S the projective special linear group PSL2(q) over the field of q elements. We determine, for all values of q > 3, the degrees of the irreducible complex characters of every group H such that S 6 H 6 Aut(S). We also determine the character degrees of certain extensions of the special linear group SL2(q). Explicit knowledge of the character tables of SL2(q), GL2(q), PSL2(q), and PGL2(q...
