Abstract:
I will present an embedding strategy
using a notion of sublinear
expander first introduced by Komlos
and Szemeredi. As applications, it
settles a conjecture of Mader in
1999 on large clique subdivisions in
graphs without 4cycles.

Gruss
type inequalities for positive
linear maps
Mohammad Sal Moslehian
Ferdowsi University of Mashhad
September 14,

(24 Shahrivar 1395)
at 16:0017:00
Abstract:
The
Gruss inequality as a reverse of Chebyshev
inequality has been developed by several
mathematicians in different contents such as
inner product spaces, Hilbert modules,
quadrature formulae and linear functionals.
In this talk, we investigate several new
Gruss type inequalities for positive linear
maps on finite or infinite dimensional
C*algebras.

Abstract:
Partial Latin rectangles are matrices
without repeated s ymbols in any row or
column, allowing the possibility of empty
cells . In this talk, we extend the nation
of "Latin square graphs" to partial Latin
rectangles, which we use to study the
symmetry groups of partial Latin
rectangles.

Abstract:
By a
classical result of Bertoin, if initially a
solution to Burgers' equation is a Levy
process without positive jumps, then this
property persists at later times. According
to a theorem of Groeneboom, a white noise
initial data also leads to a Levy process at
positive times. Menon and Srinivasan
observed that in both aforementioned results
the evolving Levy measure satisfies a
Smoluchowskitype equation. They also
conjectured that a similar phenomenon would
occur if instead of Burgers' equation, we
solve a general scalar conservation law with
a convex flux function. Though a Levy
process may evolve to a Markov process that
in most cases is not Levy. The corresponding
jump kernel would satisfy a generalized
Smoluchowski equation. Along with Dave
Kaspar, we show that a variant of this
conjecture is true for monotone solutions to
scalar conservation laws.

Abstract:
Many
reallife networks can be modeled by
stochastic processes with a spatial
embedding. For example, in a social network,
vertices may be considered as members of a
social space, where the coordinates
represent the interests and background of
the users, and the probability of a link
occurring between two vertices decreases as
their metric distance increases. A
fundamental question is to determine whether
a given network is compatible with a spatial
model. We show how to recognize graph
sequences produced by random graph processes
that have a natural embedding into the real
line, using techniques from the theory of
graph limits as pioneered by Lovasz, Szegedy
and others. This talk is based on work joint
with Huda Chuangpishit, Matt Hurshman,
Jeannette Janssen, and Nauzar Kalyaniwalla.
Embedding partial Latin squares in
Cayley tables

Abstract:
Sudoku
puzzles are examples of a combinatorial
object called a partial latin square (PLS).
In 1974 Denes and Keedwell asked for each n
what is the smallest PLS that cannot embed
into any group's Cayley table of order n. In
2012 Hirsch and Jackson asked what is the
smallest PLS that can be embedded in an
infinite group but not into any finite
group. We answer both these questions and a
couple of related ones.
