On hypersurface quotient singularities of dimension 4
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 48, Page 2547-2581, 2004., 2004 We consider geometrical problems on Gorenstein hypersurface orbifolds of dimension n ≥ 4 through the theory of Hilbert scheme of group orbits. For a linear special group G acting on ℂn, we study the G‐Hilbert scheme HilbG(ℂn) and crepant resolutions of ℂn/G for G the A‐type abelian group Ar(n).

Character induction in p‐groups
International Journal of Mathematics and Mathematical Sciences, Volume 9, Issue 3, Page 589-596, 1986., 1985 Let G be a finite p‐group and let χ be an irreducible character of G. Then χ is monomial; that is, χ = λG, where λ is a linear character of some subgroup of G. We are interested in locating subgroups of G which induce the character χ.

Restriction of Odd Degree Characters of $\mathfrak{S}_n$ [PDF]
, 2017 Let $n$ and $k$ be natural numbers such that $2^k < n$. We study the restriction to $\mathfrak{S}_{n-2^k}$ of odd-degree irreducible characters of the symmetric group $\mathfrak{S}_n$.

An update on Haiman’s conjectures
Forum of Mathematics, SigmaWe revisit Haiman’s conjecture on the relations between characters of Kazdhan–Lusztig basis elements of the Hecke algebra over $S_n$ . The conjecture asserts that, for purposes of character evaluation, any Kazhdan–Lusztig basis element is reducible

Splines on Cayley graphs of the symmetric group
Forum of Mathematics, SigmaA spline is an assignment of polynomials to the vertices of a graph whose edges are labeled by ideals, where the difference of two polynomials labeling adjacent vertices must belong to the corresponding ideal. The set of splines forms a ring. We consider

A Note on Skew Characters of Symmetric Groups
, 2016 In previous work Regev used part of the representation theory of Lie superalgebras to compute the values of a character of the symmetric group whose decomposition into irreducible constituents is described by semistandard $(k,\ell)$-tableaux.

Improved covering results for conjugacy classes of symmetric groups via hypercontractivity
Forum of Mathematics, SigmaWe study covering numbers of subsets of the symmetric group $S_n$ that exhibit closure under conjugation, known as normal sets. We show that for any $\epsilon>0$ , there exists $n_0$ such that if $n>n_0$ and A is a normal ...

All Kronecker coefficients are reduced Kronecker coefficients
Forum of Mathematics, PiWe settle the question of where exactly do the reduced Kronecker coefficients lie on the spectrum between the Littlewood-Richardson and Kronecker coefficients by showing that every Kronecker coefficient of the symmetric group is equal to a reduced ...

Partitions which are p- and q-core [PDF]
, 2001 Let p and q be distinct primes, n an integer with n > p2q2. Then there is no partition of n which is at the same time p- and q-core.

An inequality for means with applications
, 2008 We show that an almost trivial inequality for the first and second mean of a random variable can be used to give non-trivial improvements on deep results. As applications we improve on results on lower bounds for the Riemann zeta-function on the critical
