Ramification in modular invariant rings

Manoj Kummini, Mandira Mondal

Let be a prime number, a field of characteristic and a finite -group acting on a standard graded polynomial ring as degree-pres…

Hilbert-Kunz Density function of tensor product and Fourier transformation

Mandira Mondal

For a standard graded ring of dimension over a perfect field of characteristic and a homogeneous ideal of finite colength, the HK density function of wit…

On polynomial invariant rings in modular invariant theory

Manoj Kummini, Mandira Mondal

Let be a field of characteristic , a finite-dimensional -vector-space, and a finite -group acting -linearly on . Let $S = \Sym V^*$. We sho…

-density function on the class group of projective toric varieties

Mandira Mondal

We prove the existence of a compactly supported, continuous (except at finitely many points) function for all monomial prime…

Density function for the second coefficient of the Hilbert-Kunz function

Mandira Mondal, Vijaylaxmi Trivedi

We prove that, analogous to the HK density function, (used for studying the Hilbert-Kunz multiplicity, the leading coefficient of the HK function), there exists a -density funct…

Hilbert-Kunz density function and asymptotic Hilbert-Kunz multiplicity for projective toric varieties

Mandira Mondal, V. Trivedi

For a toric pair , where is a projective toric variety of dimension and is a very ample -Cartier divisor, we show that the Hilbert-Kunz density funct…
