An ultra wide-band, high-sensitivity Q-band receiver for single-dish telescopes, eQ: rest frequency determination of CCS ( $J_{N}$ = $4_{3}$ - $3_{2}$ ) and SO ( $J_{N}$ = $1_{0}$ - $0_{1}$ ), and high-redshift CO ( $J$ = 1-0) detection

Fumitaka Nakamura, Chau-Ching Chiong, Kotomi Taniguchi +16

We report on the development and commissioning of a new Q-band receiver for the Nobeyama 45-m telescope, covering 30--50 GHz with a receiver noise temperature of about 15 K. We nam…

Pseudocompact algebras and highest weight categories

Frantisek Marko, Alexandr N. Zubkov

We develop a new approach to highest weight categories $C$ with good (and cogood) posets of weights via pseudocompact algebras by introducing ascending (and descending) quasi…

Quotient sheaves of algebraic supergroups are superschemes

Akira Masuoka, Alexander N. Zubkov

To generalize some fundamental results on group schemes to the super context, we study the quotient sheaf $G / ~ H$ of an algebraic supergroup $G$ by its closed supersubgroup…

Generators of supersymmetric polynomials in positive characteristic

A. N. Grishkov, F. Marko, A. N. Zubkov

Kantor and Trishin described the algebra of polynomial invariants of the adjoint representation of the Lie supergalgebra $g l (m ∣ n)$ and a related algebra $A_{s}$ of what they called p…

On quotients of affine superschemes over finite supergroups

A. N. Zubkov

In this article we consider sheaf quotients of affine superschemes by finite supergroups that act on them freely. More precisely, if a finite supergroup $G$ acts on an affine super…
