What Quantitative Risk Modellers Can Learn from Durkheim's Study of Suicide
Mahmood Alaghmandan
Emile Durkheim's Suicide: A Study in Sociology (1897) predates much of the statistical machinery that quantitative modellers now take for granted. Yet, working with sparse and impe…
Multipliers of Beurling-Fourier algebras
Mahmood Alaghmandan, Olof Giselsson, Ebrahim Samei +1
For a locally compact group G we introduce and study the reduced Beurling-Fourier-Stieltjes algebra, a weighted analogue of the reduced Fourier-Stieltjes algebra, together with the…
A Methodology to Measure Impacts of Scenarios Through Expected Credit Losses
Mahmood Alaghmandan, Meghal Arora, Olga Streltchenko
In this paper, we present a methodology for measuring the impact of scenarios on the expected losses of exposures by leveraging the existing provisioning infrastructure within fina…
Lessons From Model Risk Management in Financial Institutions for Academic Research
Mahmood Alaghmandan, Olga Streltchenko
In this paper, we discuss aspects of model risk management in financial institutions which could be adopted by academic institutions to improve the process of conducting academic r…
Remarks on weak amenability of hypergroups
Mahmood Alaghmandan
We study the existence of multiplier (completely) bounded approximate identities for the Fourier algebras of some classes of hypergroups. In particular we show that, a large class…
A new duality via the Haagerup tensor product
Mahmood Alaghmandan, Jason Crann, Matthias Neufang
We initiate the study of a new notion of duality defined with respect to the module Haagerup tensor product. This notion not only recovers the standard operator space dual for Hilb…
Mapping ideals of quantum group multipliers
Mahmood Alaghmandan, Jason Crann, Matthias Neufang
We study the dual relationship between quantum group convolution maps and completely bounded multipliers of $\widehat{\mathbb{G}…

We provide a description of certain invariance properties of completely bounded bimodule maps in terms of their symbols. If is a locally compact quantum group, we char…
Completely bounded bimodule maps and spectral synthesis
M. Alaghmandan, I. G. Todorov, L. Turowska
We initiate the study of the completely bounded multipliers of the Haagerup tensor product of two copies of the Fourier algebra of a locally compa…
Fourier algebras of hypergroups and central algebras on compact (quantum) groups
Mahmood Alaghmandan, Jason Crann
This paper concerns the study of regular Fourier hypergroups through multipliers of their associated Fourier algebras. We establish hypergroup analogues of well-known characterizat…
Character density in central subalgebras of compact quantum groups
Mahmood Alaghmandan, Jason Crann
We investigate quantum group generalizations of various density results from Fourier analysis on compact groups. In particular, we establish the density of characters in the space…
Projections in ; the unimodular case
Mahmood Alaghmandan, Mahya Ghandehari, Nico Spronk +1
We consider the issue of describing all self-adjoint idempotents (projections) in when is a unimodular locally compact group. The approach is to take advantage of know…

Mahmood Alaghmandan, Mehdi Ghasemi
Arbitrary representations of a commutative unital (-) -algebra as a subalgeba of are considered, where or …
Dual space and hyperdimension of compact hypergroups
Mahmood Alaghmandan, Massoud Amini
We characterize dual spaces and compute hyperdimensions of irreducible representations for two classes of compact hypergroups namely conjugacy classes of compact groups and compact…
Amenability properties of the central Fourier algebra of a compact group
Mahmood Alaghmandan, Nico Spronk
We let the central Fourier algebra, ZA(G), be the subalgebra of functions u in the Fourier algebra A(G) of a compact group, for which u(xyx^{-1})=u(y) for all x,y in G. We show tha…
Weighted discrete hypergroups
Mahmood Alaghmandan, Ebrahim Samei
Weighted group algebras have been studied extensively in Abstract Harmonic Analysis where complete characterizations have been found for some important properties of weighted group…

We prove that every proper Segal algebra of a SIN group is not approximately amenable.
Amenability notions of hypergroups and some applications to locally compact groups
Mahmood Alaghmandan
Different notions of amenability on hypergroups and their relations are studied. Developing Leptin's theorem for discrete hypergroups, we characterize the existence of a bounded ap…

Separating maps between commutative Banach algebras
Mahmood Alaghmandan, Rasoul Nasr-Isfahani, Mehdi Nemati
