We derive a cancellation theorem for degenerations of modules that says in particular, that
projective or injective common direct summands can always be neglected. Combining the …

It is conjectured in [Pe2] that a so-called good algebra A is of tame representation type if and
only if its Tits form q, is weakly non-negative. In [Ke, MP, Pe 1, PT] the validity of this …

An integral quadratic form q: ℤ n→ ℤ is usually identified with a bilinear form 𝕓∨ q: ℤ n× ℤ
n→ ℤ satisfying q (x)= 𝕓∨ q (x, x) for any vector x in ℤ n, and such that its Gram matrix with …

An integral quadratic form q: Zn Ñ Z is usually identified with a bilinear form qq: Zn ˆ Zn Ñ Z
satisfying qpxq “qqpx, xq for any vector x in Zn, and such that its Gram matrix with respect to …

Let $ A $ be a special biserial algebra over an algebraically closed field. We show that the
first Hohchshild cohomology group of $ A $ with coefficients in the bimodule $ A $ vanishes …

Let K be an algebraically closed field and let I be a finite partially ordered set. To any vector
v∈ NI we associate the irreducible variety Mat vI with an action of the algebraic group G vI …
