In this paper we will give the character table of the irreducible rational representations of G=SL (2, q) where q= , p prime, n>O, by using the character table and the Schur indices of SL(2,q).

Data from 15 modern studies are used to characterize the deviations from Webcr's law for intensity discrimination of 1000-Hz tone pulses. The results show that Weber's law is satisfied in the region 10-40 dB SL, that resolution descreases with decreasing intensity below 10 dB SL and increases with increasing intensity' above 40 dB SL, and that resolution at 90 dB SL is roughly 2.5 times better ...

The aim of this paper is to raise the ethical problems which appears when hearing computer scientists work on the Sign Languages (SL) used by the deaf communities, specially in the field of Sign Language recognition. On one hand, the heavy history of institutionalised SL must be known. On the other hand, the linguistic properties of SL must be learned by computer scientists before trying to des...

A unified and systematic scheme for construction of differential operator realization of any irreducible representation of sl(n) is developed. The q-analogue of this unified scheme is used to construct q-difference operator realization of any irreducible representation of Uq(sl(n)). Explicit results for Uq(sl(2)), Uq(sl(3)) and Uq(sl(n)) are given. Research partialy supported by Sharif Universi...

Although inhibition of the sarcolemmal (SL) Na(+)-K(+)-ATPase is known to cause an increase in the intracellular concentration of Ca(2+) ([Ca(2+)](i)) by stimulating the SL Na(+)/Ca(2+) exchanger (NCX), the involvement of other SL sites in inducing this increase in [Ca(2+)](i) is not fully understood. Isolated rat cardiomyocytes were treated with or without different agents that modify Ca(2+) m...

In this paper, non-geodesic biharmonic curves in ̃ SL(2, R) space are characterized and the statement that only proper biharmonic curves are helices is proved. Also, the explicit parametric equations of proper biharmonic helices are obtained. AMS subject classifications: 53A40

The faithful lattices of rank 2(p ? 1) of the groups SL 2 (p) are described. For small primes p these and related lattices are investigated by computer. In particular a new extremal even unimodular lattice of rank 48 is constructed.

In open systems veri cation, to formally check for reliability, one needs an appropriate formalism to model the interaction between agents and express the correctness of the system no matter how the environment behaves. An important contribution in this context is given by modal logics for strategic ability, in the setting of multi-agent games, such as Atl, Atl∗, and the like. Recently, Chatter...

In the present paper, we study the group SL 2 (H Z) of (2 2)-matrices with reduced norm 1 over the noncommutative ring of Hamilton quaternions with integral coeecients. In section 1, we obtain a presentation for SL 2 (H Z) in terms of generators and deening relations. In section 2, we exhibit a subgroup of nite index of SL 2 (H Z) with a nonabelian free quotient of rank 3. It is well known that...
