On squares of odd zeta values and analogues of Eisenstein series
Dixit, Atul; Gupta, Rajat
A Ramanujan-type formula involving the squares of odd zeta values is obtained. The crucial part in obtaining such a result is to conceive the correct analogue of the Eisenstein series involved in Ramanujan's formula for . The formula for is then generalized in two different directions, one, by considering the generalized divisor function , and the other, by studying a more general analogue of the aforementioned Eisenstein series, consisting of one more parameter N. A number of important special cases are derived from the first generalization. For example, we obtain a series representation for , where ? is a non-trivial zero of . We also evaluate a series involving the modified Bessel function of the second kind in the form of a rational linear combination of and for .

Primary decomposition and normality of certain determinantal ideals
Saha, Joydip; Sengupta, Indranath; Tripathi, Gaurab
In this paper, we study primality and primary decomposition of certain ideals which are generated by homogeneous degree 2 polynomials and occur naturally from determinantal conditions. Normality is derived from these results.

Semilinear elliptic problems with singular terms on the Heisenberg group
Kumar, Dharmendra
We consider the semilinear elliptic problem: ??Hnu??g(?)u(|z|4+t2)1/2=?f(?)u?+h(?)upin ?,u>0in ?,u=0on ??. where ??Hn is an open bounded subset, N?3;0??,0?f,g,h?L?(?). Under assumptions ?,p>0,?>0 small we show that there exists a solution u?H01(?,Hn) ?L?(?) to this problem. The interesting point of the problem under consideration is that it has a strong singularity.

Gelfand-Kirillov dimension of the quantized algebra of regular functions on homogeneous spaces
Chakraborty, Partha Sarathi; Saurabh, Bipul
In this article, we prove that the Gelfand-Kirillov dimension of the quantized algebra of regular functions on certain homogeneous spaces of types $ A$, $ C$, and $ D$ is equal to the dimension of the homogeneous space as a real differentiable manifold.
