Regular ternary sums of generalized polygonal numbers
Mingyu Kim
In this article, we provide an explicit constant such that there is no regular ternary sum of generalized -gonal numbers for any integer greater than .
Composition laws of binary quadratic forms and isolations of quadratic forms
Jangwon Ju, Daejun Kim, Kyoungmin Kim +2
A positive definite and integral quadratic form is called irrecoverable if there is a quadratic form such that it represents all proper subforms of , whereas it does not…
Isolations of the sum of two squares from its proper subforms
Jangwon Ju, Daejun Kim, Kyoungmin Kim +2
For a (positive definite and integral) quadratic form , a quadratic form is said to be {\it an isolation of from its proper subforms} if it represents all proper subforms of…
Regular triangular forms of rank exceeding 3
Mingyu Kim
A triangular form is defined to be an integer-valued quadratic polynomial of the form where are positive integers and $P_3(x)=x…
A classification of regular diagonal quadratic forms
Mingyu Kim
A positive-definite integral quadratic form is called regular if it represents every positive integer which is locally represented. In this article, we classify all regular diagona…
Primitively universal quaternary quadratic forms
Jangwon Ju, Daejun Kim, Kyoungmin Kim +2
A (positive definite and integral) quadratic form is said to be if it represents all positive integers, and is said to be …
